fix(readline): change input text if it doesnt match supplied prefix for completions

changed the way file completions are handed
completely, which fixes #130 and makes the
full name appear in the completion menu instead
of it being cut off

+  - However Hilbish runs interactive user input can now be changed Lua side (`doc runner-mode`)
+
+### Changed
+- `vimMode` doc is now `vim-mode`
+
+### Fixed

+- `command.not-executable` hook (will replace `command.no-perm` in a future release)
+
+### Fixed
+- Check if interactive before adding to history

+- Completion menu doesnt appear if there is only 1 result
+- Ignore SIGQUIT, which caused a panic unhandled
+- Remove hostname in greeting on Windows
+- Handle PATH binaries properly on Windows
+- Fix removal of dot in the beginning of folders/files that have them for file complete
+- Fix prompt being set to the continue prompt even when exited

-Hilbish is a Unix-y shell which uses Lua for scripting. Things like the prompt,
-general configuration and such are done with Lua.
+Hilbish is a extensible shell (framework). It was made to be very customizable
+via the Lua programming language. It aims to be easy to use for the casual
+people but powerful for those who want to tinker more with their shell,
+the thing used to interface with most of the system.  
 
-For interactive use, it uses a library to run sh which works on all
-platforms Hilbish can be compiled for. It can also act as a Lua REPL if you want
-it to be.
+The motivation for choosing Lua was that its simpler and better to use
+than old shell script. It's fine for basic interactive shell uses,
+but that's the only place Hilbish has shell script; everything else is Lua
+and aims to be infinitely configurable. If something isn't, open an issue!

+# Getting Started
+At startup, you should see a message which says to run a `guide` command.
+This guide is a *very* simple and basic step through text of what Hilbish is
+and where to find documentation.
+
+Documentation is primarily viewed via the in shell `doc` command.
+Autogenerated function docs and general docs about other things are included
+there, so be sure to read it.
+
+Using Hilbish is the same as using any other Linux shell, with an addition
+that you can also run Lua. Hilbish can also act as an enhanced Lua REPL
+via `hilbish.runnerMode 'lua'`. To switch back to normal, use
+`hilbish.runnerMode 'hybrid'`.

+Hilbish is *unique,* when interactive it first attempts to run input as
+Lua and then tries shell script. But if you're normal, you wouldn't
+really be using Hilbish anyway but you'd also not want this
+(or maybe want Lua only in some cases.)
+
+The "runner mode" of Hilbish is customizable via `hilbish.runnerMode`,
+which determines how Hilbish will run user input. By default, this is
+set to `hybrid` which is the previously mentioned behaviour of running Lua
+first then going to shell script. If you want the reverse order, you can
+set it to `hybridRev` and for isolated modes there is `sh` and `lua`
+respectively.
+
+You can also set it to a function, which will be called everytime Hilbish
+needs to run interactive input. For example, you can set this to a simple
+function to compile and evaluate Fennel, and now you can run Fennel.
+You can even mix it with sh to make a hybrid mode with Lua replaced by
+Fennel.
+
+An example:
+hilbish.runnerMode(function(input)
+	local ok = pcall(fennel.eval, input)
+	if ok then
+		return input, 0, nil
+	end
+
+	return hilbish.runner.sh(input)
+end)
+
+The `hilbish.runner` interface is an alternative to using `hilbish.runnerMode`
+and also provides the sh and Lua runner functions that Hilbish itself uses.
+A runner function is expected to return 3 values: the input, exit code, and an error.
+The input return is there incase you need to prompt for more input.
+If you don't, just return the input passed to the runner function.
+The exit code has to be a number, it will be 0 otherwise and the error can be
+`nil` to indicate no error.
+
+## Functions
+These are the functions for the `hilbish.runner` interface
+
++ setMode(mode) > The same as `hilbish.runnerMode`
++ sh(input) -> input, code, err > Runs `input` in Hilbish's sh interpreter

+If you ever want to run a piece of code on a timed interval, or want to wait
+a few seconds, you don't have to rely on timing tricks, as Hilbish has a
+timer API to set intervals and timeouts.
+
+These are the simple functions `hilbish.interval` and `hilbish.timeout` (doc
+accessible with `doc hilbish`). But if you want slightly more control over
+them, there is the `hilbish.timers` interface. It allows you to get
+a timer via ID.
+
+# Timer Interface
+## Functions
+- `get(id)` -> timer: get a timer via its id
+- `create(type, ms, callback)` -> timer: creates a timer, adding it to the timer pool.
+`type` is the type of timer it will be. 0 is an interval, 1 is a timeout.
+`ms` is the time it will run for in seconds. callback is the function called
+when the timer is triggered.
+
+# Timer Object
+Those previously mentioned functions return a `timer` object, to which you can
+stop and start a timer again. The functions of the timers interface also
+return a timer object.
+
+## Properties
+- `duration`: amount of time the timer runs for in milliseconds
+- `running`: whether the timer is running or not
+- `type`: the type of timer (0 is interval, 1 is timeout)
+
+## Functions
+- `stop()`: stops the timer. returns an error if it's already stopped
+- `start()`: starts the timer. returns an error if it's already started
