Package with distutils.core

This is a first cut at packaging python-adb with distutils setup.

Moved source for module "adb" to directory "adb".
Added adb/__init__.py
Updated and ran adb_test.py and fastboot_test.py.
Added setup.py to build and install module.
Yeah, it should include someone actually still on the team. I'm off doing my own thing now, so my interest in this project is more out of nostalgia than actual need :smile: I'm cool with the author being me and the maintainer being whoever wants it.
