Implemented support for rooms

I implemented full api support for rooms. That means:
- Create/Modify/Delete rooms/lightgroups
- Get information about group list / individual group
- Group actions: Change lighting for the whole group (except setting scenes, because scenes are not implemented in ha-bridge right now)
For now the rooms/groups can only be configured through the api and apps, it's not visible/changeable through the web gui.
