version bump; please update rubygems.org gem

**tl;dr** -- gem on rubygems.org needs to be updated, so version bump.

notes from skype:
```
[6/14/13 2:58:54 PM] Mike Tigas: 1) warbler does not bundle the tabula-extractor gem properly (maybe because it is named "tabula-extractor" but it is "lib/tabula" and "lib/tabula.rb"). 
2) big issue with hash vs fixnum fixed with https://github.com/jazzido/tabula-extractor/commit/bbd38ebbced34065cda661c74c45d98b9f1c4966 so gem on rubygems.org needs to be updated
[6/14/13 2:59:10 PM] Mike Tigas: that was the whole problem
[6/14/13 2:59:59 PM] Mike Tigas: jruby on my Win64 box actually is running in 32bit mode (JRE looks to support both, but i guess it boots 32 by default) so 64bit dll wasn't necessary
[6/14/13 3:00:10 PM] Mike Tigas: rulings debug seems to work now
