update to devise 2.1
just make it devise 2.blah
Update to use >= 2

Current devise is 2.1 but some inter-related gems I need require devise 2.0

as a quasi-annoying solution, just say anything greater than 2 and let other gems use what they need
zeus crashing without specifically defining require of devise
gemspec specifies rails >= 3 for testing/development.

Recently Bundler has been installing Rails 2.3 as a default,
when no version is specified.
Merge branch 'santouras/master': update devise dependency.
Incremented version from 0.1.3 to 0.2.0
