bc29082f9d Remove use of "%n" to appease de Raadt 
Sure, it was completely unnecessary, but I resent being told how
to use snprintf.

bc3bd95648 Drop filesystem access iff possible 
Log files and state save/restore both require read/write access to
the filesystem, both during start and exit.

If neither features are used, catgirl may run with "stdio tty".

c93c56e4e5 Drop network capability after ircConnect() 
catgirl has no reconnect feature and generally must not do
anything but read/write from/to the connected socket which
does not require "inet" or "dns" promises.

a19f48d840 Call pledge(2) after unveil(2) 
Simplify logic, be more idiomatic and finalize by pledging after
all unveiling is done by omitting the "unveil" promise and thereby
not allowing further calls to it.

95bb627ffb Separate kiosk mode from restrict mode 
Restrict mode will focus on sandboxing, while kiosk will continue
to restrict IRC access through a public kiosk. Kiosk mode without
restrict mode allows execution of man 1 catgirl with /help, assuming
external sandboxing.

The /list and /part commands are also added to the list of disabled
commands in kiosk mode, since they are pointless without access to
/join.

6ee0aea9e5 Simplify windowUpdate loops and factor out windowTop 
No idea why I made that more complicated than it had to be looping
backwards.

cdff668d8f Allow interspersing flags and config files 
Don't wait for getopt_long to move all the arguments to the end. This
allows overriding options set by config files by placing flags after
them on the command line.

a324795b86 Allow configuring the upper bound of the hash function 
This allows limiting the nick colors used to the 16-color terminal set
without modifying the TERM environment variable. Produces different
results from just using the default configuration in a 16-color
terminal, but what can you do?

3b54425ec1 Collapse whitespace while wrapping and discard trailing space 
The latter avoids an extra blank line when a message ends with
whitespace that hits the edge of the window.

4b883177dc Split ignore fields to avoid over-eager * matching 
Split ignore fields and match each separately to avoid an early *
eagerly matching across several fields. For example, "* JOIN * *" should
not match messages which happen to contain the word "JOIN" followed by
two other words.

Ignore capacity is reduced to 64 to keep the size of the array the same.
I don't think it's an issue.
