quick and dirty (emphasis on dirty) debian changelog generator

This generates an up-to-date ```debian/changelog``` from ```src/CurrentBuild.txt``` for creating packages.  It's mostly an ugly hack using awk, date, and bash.

Users should run this before running ```debuild```.  **Note**: Make sure to update ```$builder``` and ```$email```, if you care about that sort of thing.

See: Issue #40 for more information.
