Removed unused global

Added some debugging

Create new bserv binary

Herein lie the following ideas:

- change package visibility of many things
- try to stash the globals into structs
- the code is far from correct; it merely compiles

This finalizes the work on getting the server to support multiple encodings for
players and spectators.

Typically client offers supported encodings, then the server chooses the
optimal one.

This is the first step involved in letting go clients talk gob to the game
server.

Still missing: actually use the client's prefered encoding

unfortunately there is an issue with how these are calculated, and they don't
decrease as things quiet down. Well, the bad numbers are their for your
consumption, and should Just Work TM when appropriate changes in
bitbucket.org/smcquay/bandwith land. And they will. But I'm tired now.

As it turns out there are other citizens of this world, not just the botclient.
So I have properly labeled the payload with a type. This makes the web
front-end less breaky.

- removed comment-disabled code
- reduced verbosity in protocol logging

- stats are now based on a 1-100 ranged and mapped to sensibles
- turnspeed and fire rate are available stats
- bugs in movement are squished

Mainly adding some comments, and some function renaming

turns out we were never exiting the loop even when all bots left. Games now
shut down when there ever has been bots and they all leave (or are killed,
I think).
