Warbler!

Warbler has some annoying habits, so we hack its brain.  I'll probably care later, but I don't right now.

Specifically, it seems the gemspec trait will inline my project tree into any produced archives, no matter what.  Open the class and disable it.  It appears warbler wants all jars which do not use the gemspec trait to use the "no gemspec" trait, so similarly enable it.

Finally, the no gemspec trait apparently has no means for naming the default binary for jar execution.  When it is not named after the jar itself (say, because the jar bears a version) this produces an annoying warning.  Punch the binary name in as well.

Also fix some chicken-egg problems re: maven dependency resolution.
