- Added fixed length bit sets.
-Fixed a bit the implementation of the fixed bit sets. Now they kinda go
around multiple dispatching with the "to" methods. Hopefully that makes
them easily inlinable.
- Also set up ComponentManager, Aspect and Entity so they use the fixed
bit sets.
- Setup a constant in DAConstat that specifies how many words each fixed
bit set will have.
- Added getWord(index) to FixedBitSet.
- Added "equal intersection" test for allSet in Aspect. It tests if the
intersection of the entity bit set and the 'all' bit set is equal to the
'all' bit set, if it is, it means the entity has all the components.
Otherwise it rejects the entity.
