Vector Fix, Prob Fix, and Integration Beginnings

Integration
Modified ExtendedCreature to accept an array of CommandBlocks
Modified CreatureHandler and ChangeTree to accept ExtendedCreatures

CreatureHandler
makeChange(Change c, int blockIndex) will always make a new
ExtendedCreature if the blockIndex is valid
Reduced the default step size and step change multiple
the changes to the vectors will now only rotate around each other
(changes also in ChangeTree and EnumChangeType)
ProbChart and ProbModule
have been changed to be Float-based
Fixed a problem in ProbModule that was making decrRange increase the
range
