"Finished" class plugin

With this commit, the very first plugin is finished! Now bots *should*
be able to identify the class of it's allies

This is entirely untested
Fine tuned bot timeout for stop existing

After some testing with maxed out respawn times, 80 seconds seems to be
the absolute maximum time a bot can stay dead, so that's the timeout
limit for deciding that a bot no longer exists
Began fixing a bug breaking self-class identification

The class toolkit does not correctly display the class of the bot that's
running the check. This means that a bot can know the class of any
allied bot except for itself (I know this is completely replaceable by
normal blocks, but I'm doing this for the sake of completeness). This
commit is the first step towards fixing this bug, will continue work
tommorow
Finished fixing issue with self class reporting. Now reports own class properly
Corrected an issue where self reporting sometimes overrode the incorrect counter
Reduced the frequency of class checks heavily. Class is now only checked every 50th tick
Began work on a States plugin
Tentatively finished state sending logic
