Added a pinging system inside of main

This system implements the already created messages and should be a
little more elegant
Added a plugins system

This should allow for easy expansion. All that's necessary for the
plugin maker to do is link their plugin to the provided plugin file
Began work on a class identification plugin

The concept is straightforward, but requires a good deal of legwork
still. Currently around 50% finished
Fixed a bug pointing to the a nonexistent file

This should load the "Class" plugin properly now
Reduced the timeout on bots for alive/dead

This means bots will recognize when allied bots have died 5 seconds
faster, at the cost of accuracy (theoretically, though, in practice, a
bot that remains unresponsive for 5+ seconds might as well be considered
dead)
Fixed issue with naming conventions

Just mass renamed some counters
Merge pull request #5 from chaorace/master

Better integrated pinging and plugins
