add/remove individual lines to/from staging in the diff view

[snoblenet]

I would love it if we could add/remove individual lines to/from staging in the diff view.

I imagine:

• j and k to move up and down in diff view
• current line in diff view highlighted somehow (configurable UI)
• a margin indicator for each line showing whether it is staged (and/or staged lines are in the bold font or colour reversed)
• c to toggle whether the current line is staged

This is one of the features I want most in the app. I'm not sure how to go about it though, it will probably require having a look to see what similar git-ui apps do in terms of which git commands to call or how the required patch files would be generated

Looks complex. But you might get somewhere parsing the output of git add -e?

I've whipped up a PR that I think does the job pretty well. The only issue is that once you've staged a file there's no clear way of how to reverse it. Either way please let me know your thoughts on that PR :)
