Initial code for the Python bindings, adding math angle types. Only the double ones, exposed as floats, because the extra ALU required by doubles is negligible to function call overhead. It'll be different for non-scalar types, but here I use this.

#include "magnum/bootstrap.h"
python: put everything into a single module if magnum is built statically. That makes it much easier to handle in that case (because that's the whole point of static builds) and also nicely circumvents any issues with duplicated global data when a static lib would be linked to multiple dynamic libraries.
