StGit: kha/{stable,safe,experimental} updated

I've rebased my branches on top of Catalin's latest master and stable. They include all the patches I've sent to the list recently.

I've added a "stable" branch, for patches intended for Catalin's "stable".

In the experimental branch, I've updated the reset command a bit -- it should now be quite usable. Bug reports and feature requests and general comments welcome. (Note to those who already run my experimental branch: I've changed the stack log format, so you'll have to nuke your <branchname>.stgit branches. StGit will remind you if you forget.)
