Rewrite compilation / install using python

Depending on Makefile +autotool + configure to build guake is hard to maintain. Actually it is pretty anwful. I would prefer to only depends on a compilation script written in pure Python 2.7, since this is a dependency that needs to be satistified in order to use guake. We may keep Makefile for the C module only. Or maybe CMake to build the C module. Or hardcode the 3 calls to gcc and ld needed to build the .so file.

Also, the module should be handled by a nice setup.py, and could be pushed to pypi.

And then, we can publish guake to pypi.
