Implement Arbitrary for (almost) all types 

Rot4 and Iso4 had to be left out, since Rot4 apparently lacks a working
constructor.

Thereby (almost) all types in nalgebra can now be used for quickcheck-style
testing.

"arbitrary" is now a conditionally compiled feature that contains these impls
adding a dependency on quickcheck.
