This was a problem before when the probe hit an object that was further than
another object first. Now we traverse all objects all the time to find the
closest one. \o/

These changes were done by running the following command:

    gofmt -s -w *.go

Has dependent change on client

Also, removed a bunch of overly verbose 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

I just moved some old code into the game struct; probably still merits some
cleanup in the main loop.
