#4826: change return type of G.cusps() for G a congruence subgroup

As pointed out on [http://groups.google.com/group/sage-
nt/browse_thread/thread/f0a95b54181ba6c5 this] thread on sage-nt, it might
be more reasonable to have `G.cusps()` return a list instead of a set (for
`G` a congruence subgroup). In particular, seeing an ordered list as
output makes it easier to look through.
The attached patch changes this return type, as well as making a few small
fixes so that this is just as fast as before (or faster, in some cases).
This patch depends on #4747.
