Title: Here comes the new SubsetStack system

Every class which should have subsets now has a variable of type CSubsetStack instead of CSubset.
Its possible to add as many as you like, works like a stack
All the logic is now in the stack, so the classes (currently Features, Labels) dont have to do anything but just provide wrapper methods

The CSubset class has changed and is now a wrapper for the SGVector of indices.
Currently, all index sets are copied when a CSubset is created in CSubsetStack, however, as soon as there is ref-counting for SGVector, this should be changed.
