Pixmaps move - for review only - DO NOT MERGE

This is not fully functional yet, but is intended to begin addressing #126. It will build a package with everything installed as intended, but the moved icons are no longer seen by blueman. Maybe I'm misunderstanding something, but if Functions.py is imported everywhere it's needed, I don't get why they're not showing up. I'll poke at it more later, but I've got out-of-town visitors arriving early tomorrow, so I've got to give up for now...
