Added a Makefile that can do lots of things.

including:

make #maps to `make rpms`
make install # installs using python setup.py
make sdist # generates tarball
make rpms # makes SRPM and RPM
make srpm # make SRPM
make clean # cleans up all the 

and a few more things.

Also, updated gitignore to not touch the build and output directories from this process.
