make cython natively support embedding

This could be done via, e.g., a command line flag.

Especially using Python's "freeze" tool sounds interesting. It might allow us to try to compile all dependencies recursively, and compile the resulting .c files statically into the resulting executable, so that we only need to include the normal .py files when their compilation fails. That way, you'd always get a complete binary from whatever you compile, just with some slower (interpreted) parts that Cython cannot compile.

Just run cython with the --embed flag, and the resulting .c file has a main method ready to go.

Of course there's lots more one could imagine doing, but this is a start.
