Updated xeno ability code.

Updated ninja ability code.
Misc ninja update.
Fixed chemistry reagent code for the ninja suit.

This final update could have been more awesome but whatever.
I've copy-pasted the ninja info on to SpiderOS for future reference.
It's been fun but now I must sayonara. Whatever that means. Oh, it means goodbye.
~Later~
