Culling Implemented

For now it's only from 3 days ago, but I will be growing the culling algorithms over the next few days/weeks.

Fix for btrfs full paths

v0.7.2

fix to add full paths for btrfs send/rec

Fix for PyPi

v0.7.1

fixing tag

Remote snaps are here now

btrfs send | receive. Assumes you have a passwordless ssh setup.

Didn't specify xdgenv version correctly in setup.cfg

v0.6.0

fixing cfg import - I hope

Messed up on the setup.cfg

Should be OK now.

Snapshots work

Haven't reimplemented culling yet, but that's going to come after the remote backups.
