1) ABS is now published as an AAR, so we can eliminate all local
dependencies and bundled jars.
2) Upgrade to ABS 4.4.0 (The Last Release) and deal with the loss
of Sherlock.Dialog by faking it with our own themes.
3) Remove all traces of ant. The modern world is here.
The current release of `ActionBarSherlock` uses tags to store its relases, so the clone command fails. Instead, clone HEAD and switch to the 4.2.0 tag.
