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.
I'd call it 1.1.0 since it works and now has TCP support, which was minor. If I were to publish it, I'll add categories and some of the other info usually found in pypi packages. I'll wait for this pull request to get in first though
