CHANGELOG:

• Conference and content floor members are now standardized;
• The floors commands now include the previous floor in their info along with the current floor and carry media info objects instead of ids;
• Turned the floor and previousFloor into optional parameters. If there are none of such in the media controller, the response will simply not include those keys in the body;
• Also removed the need of passing the floor id in the release methods;
• Added some of the missing method docs.
