stashing support

[extrawurst]

some question need to be solved for this:

• does the stashing happen in the status tab? or..
• we will need a new tab for the stash list anyway, is that the place to also save stuff to the stash? this would allow setting the options like include untracked files?
• if we stash in the status-tab, do we use a popup to ask for the options like that?

I think I am going for a two tab approach now

This looks useful! One thing that would be useful that I don't see above is being able to stash individual lines or hunks rather than full files, like git stash push --patch (but with a better UI). I can raise this as a new feature request for later down the road (if you think it's a worthwhile enhancement, that is).

[extrawurst]

Yeah that's actually two feature requests. Stashing individual files was on my list (which we need the upstream lib to add support for first: libgit2/libgit2#4725), but stashing hunks actually never crossed my mind 🙈

[jugglerchris]

Thanks, I've raised a new feature request for stashing hunks.
