Re: StGit kha/experimental branch updated

Even more things polished now, to the point that I think this could be merged soon (but after 0.14, obviously).

The most recent fixes are:

  * Say "current" and "patched" in conflict markers instead of the
    trees' sha1s; this was a regression introduced by the conflict
    series.

  * All the various "top" and "bottom" files are written again, for
    backwards compatibility.

Testing would be much appreciated.
