VSE: Add Overlay popover panels

Add panels with overlay settings for strips and preview and overlay
enable/disable button.

Entries from the View menus moved to the overlay panels, which will
simplify cluttered View menus.

Additional options have been added:
 - Strip Name
 - Strip Source(ex. path)
 - Strip Duration

So users can now select what info they need to see on the strips. When
No text is displayed, waveforms are drawn in full height.
