Update room properties from room details (#439)

-  Add the edit action in the room details
-  Add "Add topic" button in room details
-  Add the screen behind that action to edit some room properties: avatar, name, topic
   -  Handle the save button action
      - enable the button only if changes are detected
      - display a loader "updating room"
      - display an error dialog if any request has failed
- Check user has the right power level to change various attributes
   - "Add topic" is only shown if there's no topic and they are able to set on
   - Edit menu is only shown if they can change topic, name or avatar
   - On the edit page, any fields they can't change are uneditable
