Re: Inital Deb Filter

Ok, sorry It's been so long (boo Comcast) but here's the .deb filter
with most of the changes we talked about. Some of the formatting stuff
in HACKING wasn't super clear because of the odd syntax of this
filter, if I missed anything else, please point it out, and I will be
more than happy to fix it.

I also added a 'Package' tile for beagle-search. At the moment it
doesn't display much extra, but it can easily be configured to show
dependencies and the like. I was thinking about adding an 'Install'
option in the context menu any thoughts on that?

This should be all you need to test it, I can't figure out how to get
cvs to include new files in the diff, if anyone knows and wants to
share, that would make this easier.

Otherwise, I await your critique.
