Dependencies are too restrictive

[unders]

Right now dm-rails is depending on railties ~> 3.0.4, this means that even though Rails 3.1 is guaranteed to be API compatible (they claim to follow semver), dm-rails is not usable with Rails 3.1, for no good reason whatsoever.

The dependency should be relaxed to railties ~> 3.0.

@unders the dependency will be bumped to ~3.1.0 once a) rails 3.1 is out b) somebody makes dm-rails to work with rails 3.1

BTW - rails doesn't follow semver.

and the active-record internal API is not backward compatible, i.e. the jruby activerecord libraries need to follow these changes before they work again. - my 2cts ;-)

I would like to use to use dm-rails with rails 3.1.0.rc6 and get the following dependency issue:

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    dm-rails depends on
      actionpack (~> 3.0.0.beta3)

    actionpack (3.1.0.rc6)
