Add compatibility for pure command-line use?

[fosspill]

Hello!

It would be wonderful to have support for pure command-line use (for those of us who dislike buttons and stuff).

I'll start fiddling with this on my own repo, but I'd like to leave this issue open in case anyone else (that actually know what they are doing) wants to help out :)

added a console.py which is at least a start :) .... good idea btw. it checks all addons and updates that which needs an update.

That's awesome! Now we just need some switches and arguments so we can add new Addons and remove them there.

Awesome work @ephraim.
