Allow permanent add of repos with collapsible folders in the repos pane/sidebar

[dkebler]

Smartgit just decided to change their free policy and I don't have enough github commits to qualify even though I don't use opensource projects to make any money. So....I went looking for a new gui client and I'm happy to have found this project!

Smartgit was always overkill for my needs so gittyup works for me!

About the only thing I'd like GIttyupt to do is to manage repos a little better since I do have dozens of repos to manage

So my idea is that the repo pane should support permanently adding (removing) repos and then being able to organize those repos in collapsible folders. Actually not my idea but rather the one thing I liked about smartgit (although I didn't care for how they did it).

Unfortunately I'm not a cc++/Qt coder so I'm not likely to be much help with coding without a learning curve, but I can help out with this project how I can. Help manage issues? Help with answering discussions? Documentation, readme, wiki, wepage? I also use Manjaro could help making sure the AUR build is up to date and this project gets consider for regular a community repo.
