Memory leaks exposed by modular symbols

Michael Abshoff, Martin Albrecht, Burcin Erocal, Willem

Jan Palenstijn, Clement Pernet, William Stein: memory leaks exposed by modular symbols functionality [this ticket is a composit of numerous other memleak fixes merged over a *7 months* period. Modular forms are an excellent way to expose memory leaks in pretty much every algebraic component of Sage and all know issues there are now finally fixed]

Graph theory: chromatic polynomial

An algorithm originally written in C by Gordon Royle has been adapted to replace the old slow method. This algorithm uses a cut and merge algorithm to recursively compute the chromatic polynomial, and is written in Cython.
