Launchpad integration

Why
GiftWrap should have Launchpad integration such that


 * a user can upload a package to their PPA
 * launchpad also builds for them in a clean enviroment and for both 32bit & 64bit
 * removes a need for having a local building enviroment

How
Requires a Python coder, see 'Archive' section of the following: https://launchpad.net/+apidoc/ for documentation.

From what's known at this point is that it'll be a different sub-program - GiftWrap itself won't be Python. Need to decide on the best communication way though. Likely will use DBus.

Features:

☐ Upload packages to users ppa. Launchpadlib does not allow this so it will be done using dput (needs discussion )

☐ Create PPAs. This will require opening up a web browser on the appropriate launchpad page to confirm (needs discussion )

☐ List all PPAs a user has

☑ List all packages in a given PPA

☐ Delete packages from a given PPA

☐ Move/copy packages between PPAs

☐ Change PPA description

Anything else?

When
This can be started on at anytime by someone experienced with Python.
