Fixed bug that caused VideoSync to sometimes connect to the wrong room. Also now saving the last used room.

Removed permissions for notifications and webNavigation. Now all notifications will show up on the video if possible, and if it is necessary to search for the video inside the iframes, the first search will grab the iframes, while the second one will request the permissions.

Now accessing all sub-frames when searching for a video in a tab in order to support iframe-embedded video players. This will request further permissions when selecting a video.

Removed need for hosts permission. Now joining room is done through the popup.
