Download packages from git

[rukai]

Downloading packages from a git repo would be really cool. Features:

• automatically git pull new changes from the repo
• package treeflection commands to handle
  • git commit; git push
  • git reset --hard origin/master
• short updates (only download new commits) / long initial download (have to download EVERY commit)
• Easier to setup/learn (via github) then my hacked together http system.
• git diff!
• encourages collaboration
• Free hosting! :P
• Music/SFX files in git erggh. (actually this might be reason enough to scrap the whole thing)

One problem would be maintaning the published flag in this new system. Maybe we wont need it anymore?

Maybe this doesnt actually help and having the extra publish step is helpful. Would have to be the same or more ergonomic than package:publish, then send zip to friend, click drag zip to window

Not sure if this should be an extra option or replace the existing http + zip package download.
