[PATCH 0 of 8 v2] save multiple comments at once

[Jan Heylen]

Hi,

as you might know, I've been working on a change that a user would allow to
open multiple comments on a commit, and 'post' (save) them all at once to the
kallithea database.

This patchset implements this workflow, by changing the 'comment' button
on inline comments to a 'save' button and having a bottom 'commit all comments'
button that will commit these draft comments as real comments.

That way, it becomes possible to review a whole commit, and only submit your
comments when you're finished reviewing the commit, and  only one summary email is sent.

All tests pass, and I've added some test to check the inner working of drafts.

please review and comment again,
