Make bots' code optional

[GoogleCodeExporter]

Overall description:
Place bots' code into ifdefs such as "USE_BOTS" since we don't want to
support them and they are almost useless in net games. We may change them
later by a better artificial intelligence.

Or to remove them completely.
I found very interesting idea about locust bot for Quake3 from Game programming 
Gems 
v.6 book. It is totally different approach. I think we better to use a 
completely new 
bots instead of current ones.
Still we'll postpone this removing until critical features for first release 
won't be 
done.
After we'll get first testing server - the bots could be removed.
