Hey, can you include a spreadsheet with your equations implemented in it?

The shear number of factors that we are using makes it very hard to evaluate how
well a set of equations works through playtesting alone. I think that we should
figure out the equations we want to use, and not worry about the actual
implementation yet, especially since the results are randomized to +/- 20% anyways.

To me the most important thing is that repairing the bots is:
1) fun, as in not freezing for too long, and 
2) balanced, as in not making the game too easy (e.g. repairing a Sawmill bot in
one second with no other penalty).

All of the other factors are by far secondary. It would be nice (but not
necessary) if the penalties went down as Tux improved various skills.

I think that the bot healing rate ( Druidmap[bot->type].healing_friendly ) can
be used as a proxy for the size of the bot. However, since this value is also
dependent on the difficulty level I think it might just be better to explicitly
use the difficulty level and the size of the bot here.
