Extend doorkeeper 3 with its extracted ORMs

doorkeeper 3 has not been released yet, and will be when its ORMs are
successfully extracted and tested into this project.

This PR extends doorkeeper with the ORM specifics for mongoid and
mongomapper.

To test it, it loads doorkeeper as a submodule, copy its test suite into
this project, configures the ORMs according to the matrix defined in
`.travis.yml` file, and run the test suite with each.

Renames project from `doorkeeper-orm` to `doorkeeper-mongodb`.

-====
+## Installation
 
-Doorkeeper's extracted ORM specifics.
+doorkeeper-mongodb provides doorkeeper support to MongoMapper, Mongoid 2, 3 and 4.
+To start using it, add to your Gemfile:
 
-including:
+``` ruby
+gem 'doorkeeper-mongodb'
+```
 
-- Mongoid2
-- Mongoid3
-- Mongoid4
-- Mongo mapper
+Run [doorkeeper’s installation generator]:
 
-### License
+    rails generate doorkeeper:install
 
-MIT.
+[doorkeeper’s installation generator]: https://github.com/doorkeeper-gem/doorkeeper#installation
+
+This will install the doorkeeper initializer into
+`config/initializers/doorkeeper.rb`.
+
+Set the ORM configuration:
+
+``` ruby
+Doorkeeper.configure do
+  orm :mongoid2 # or :mongoid3, :mongoid4, :mongo_mapper
+end
+```
+
+### Mongoid indexes
+
+Make sure you create indexes for doorkeeper models. You can do this either by
+running `rake db:mongoid:create_indexes` or (if you're using Mongoid 2) by
+adding `autocreate_indexes: true` to your `config/mongoid.yml`
+
+
+### MongoMapper indexes
+
+Generate the `db/indexes.rb` file and create indexes for the doorkeeper models:
+
+    rails generate doorkeeper:mongo_mapper:indexes
+    rake db:index
+
+
+## Tests
+
+To run tests, clone this repository and run `rake`. It will copy and run
+doorkeeper’s original test suite, after configuring the ORM according to the
+variables defined in `.travis.yml` file.
+
+

+
+Please refer to https://github.com/doorkeeper-gem/doorkeeper for instructions on
+doorkeeper’s project.
