Made a release this morning, mostly because the release earlier this week turns out to have accidentally removed several options from git annex copy.

Spent some time this afternoon improving how git-annex shuts down when --time-limit is used. This used to be a quick and dirty shutdown, similar to if git-annex were ctrl-c'd, but I reworked things so it does a clean shutdown, including running any buffered git commands. This made incremental fsck with --time-limit resume much better, since it saves the incremental fsck database on shutdown. Also tuned when the database gets checkpointed during an incremental fsck, to resume better after it's interrupted.
