I resolved some conflicts and repushed, so it should merge now. /cc @wagenet

As always, feel free to cherry-pick if you're unsure about some of the commits.

@joliss, now that we have 0-9-stable, I'd like for all applicable commits to go there first. 0-9-stable will then be merged into master. To that end I cherry-picked the first 4 commits to 0-9-stable and the last one to master.
