Rework scroll window implementation

Browse Source 
This complete rewrite of the scroll window implementation decouples
scroll windows from every other window abstraction layer we use. Note
that this leads to some code duplication. The long-term purpose of this
rewrite, however, is to eventually make every panel use scroll windows.
This makes for a huge cleanup of the UI code.
