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".

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.

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.

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.

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?

Bump ParamCap to 254
...
Apparently IRCds have decided that the 15-parameter limit doesn't matter
anymore. 254 is the maximum number of single-byte parameters (following
a single-byte command) which fit in a 512-byte CR-LF-terminated line.
When everyone decides that the 512-byte line length limit doesn't matter
either, I will delete my software and people can use some JavaScript
garbage instead.
This makes struct Message 2080 bytes, but there's only ever one or two
of them around at once. Avoid passing it by value to handle.

using this fix for a couple weeks though and it stopped happening, and
it's otherwise harmless, but yikes.
