Added some bots!

Hello,

Ok, I finally got the bots going, they're not too smart as yet but that's OK for now.

It was a bigger job than I expected as I ended up doing some major reworking of several networking bits. This allowed the game to start with a 'bots only' attract mode that will theoretically add 3 bots for everyone who views the skirmish page before they even join the game!

This is something I always wanted to get going but wasn't sure if I should put off until things were a bit more mature, but it didn't turn out to be a huge deal after I'd cleaned up a few other things.

But doing all this has rasied an interesting question - do I need a privacy policy of some kind? Currently I don't send any information about your setup to my raspberry pi server (actually, this is not 100% true, I do send what build type you are running, although this is currently 'browser' for everyone in the world except me who has the world's only 'desktop' build!).

But in future I would really like to send some 'config' info, eg: GL_RENDERER, GL_VERSION, GL_VENDOR strings, maybe GL_EXTENSIONS to help with debugging, and for that I think I should probably make sure user can opt in/out?

Bye,
Mark
