Merge pull request #137 from macnibblet/hotfix/embedded-support

Add support for 2.5 embeddables
Changed the MongoDBPurger class to only clear collections, not remove them.

Instead of dropping all collections, we should remove all documents in a
collection instead. This avoids problems where indexes are lost while dropping
the collection, and collections not being recreated (with a schema create tool)
while loading fixtures.
Merge branch 'mongodb-purger-fix' of github.com:gerryvdm/data-fixtures into mongodb-purger-fix
