Minor dev release - 0.5

I updated the sim to expose more variables to play with. The min difficulty for the bot to make a check will make the bots more reckless as the values get higher (meaning they will attempt harder difficulties even though they may not succeed). The default for this value has been 9, but feel free to play with it. Making the value lower will make the bots more risk adverse.

You can now play with how bots request power, and how long bots wait to shoot or transfer power (engineers do this when the difficulty to pump the engines is too high).

Enjoy!
