A better travis-ci build matrix

of 2.1 is being removed entirely.
Loosen version constraints for Rails libs

In anticipation of Rails 4.0, these need to be looser.
Add specs for exposure setters

These have been a part of DecentExposure since before the release of
2.0, but somehow the tests didn't make it in.
Don't clobber parent configurations
Use 1.8 style hashes for compatibility
Introduce strategy for use with strong_parameters

This works similarly to ActiveRecordWithEagerAttributesStrategy, but for
attributes to be assigned, you must provide the name of the method to be
called, via the :attributes option to the `expose` call.

The assumption here is you'll define a private method in the controller
and use strong parameters, as:

    expose(:foo, attributes: :foo_params)

    def foo_params
      params.require(:foo).permit(:bar, :baz)
    end
Add documentation for strong_parameters strategy
