New description:
This upgrades the group algebras to the current coercion system and fixes
some issues of multiplication of group algebras A and B, satisfying A == B
but not admitting coercion of elements.
This depends on #6669, which concerns homomorphisms from matrix group to
other objects.

Comment(by mraum):
I attached a patch that changes the way functors are called.
Also I reviewed the parts that you implemented. That is, the transition to
CombinatorialFreeModule. I would give this a positive review. So if you
agree with the procedure that I described above and are fine with the rest
of the code you can give this a positive review as a whole.
