Proposal for Abstraction Layer for Modifications in Bug.pm

	OK, sounds good. In case we ever go fully object-oriented with
Bugzilla, I think when you create a bug it should have a flag called
"comitted" that lets us know if it's actually in the DB or not. Of
course, this could already be there, and I could just be unaware of it.
