exception with boosting creeps with CLAIM parts

[bonzaiferroni]

I ran into an issue when trying to boost a creep that had claim parts. 

After trying to find the cause in my own code, I noticed it would go away when I just commented out lab.boostCreep. I asked another player to try to boost a creep with claim parts and he reported that he would also get the same exception. 

Perhaps this is because BOOSTS[CLAIM] is undefined?

This is indeed a related to the fact that `BOOSTS[CLAIM]` doesn't exist.

I've filed a pull request to fix this behaviour.

I will bring this to the developers attention. Thanks for reporting and testing it.
