Show stagedness status in tree-view about github HOT 7 OPEN

@simurai any idea what this would look like?

from github.

Was thinking since we color the current git-diff lines, we could do the same in the tree-view. For partially staged files, the line could be dotted.

Currently the tree-view adds classes like: status-modified. So we could add these additional classes: status-staged and status-staged-partially
status-staged-partially?

Or maybe better to name-space it with git- so it's easier to remember that this comes from the git package:

• git-status-staged
• git-status-staged-partially

Anyways, as long as you add "some" classes, I can do the styling for it.

One question is: Should a folder containing a staged file also show the staged line? To be consistent with the current diff coloring, I would say yes. So in the mock above, the "lib" folder would be orange and also have a git-status-staged class and therefore a blue line.

There was also the idea that you can stage/unstage/discard in the tree-view, maybe with a keybinding or mouse:

But if at all, maybe less priority?

I have the same questions about implementation here as I do in #45 (comment).

After mulling this, I think we should 👢 it from this milestone. This seems like a nice integration to have, but I think there are more important things we should do first.

@simurai Thoughts?

👍 on 👢ing this. Especially because it's an alternative to an already existing feature (staging from the panel).
