Build status, installation section, cosmetic updates, another usage example

- Cleaned up summary
- Added build status

- Added example usage of `label_value_pairs` for an ActiveAdmin form
Moved rspec-rails gem to test and development environments.
Fixed incorrect instantiation of 'User' without 'role:' key in usage examples.
Support filtering in method `label_value_pairs`

The method `label_value_pairs` can now take multiple symbol arguments
to filter the returned array of pairs by enum keys.

Example:

    User::Role.label_value_pairs(:admin, :author) == [
      ['Admin', 0], ['Author', 1]
    ]
Change description and temporarily stop using FG

- Updated the top description string for `describe`
- Temporarily changed test user creation to default Rails API
  because I'm having issues with other tests and FactoryGirl
