#299 Dock (glue) windows together

[Radu Stefan]

I would like to be able to glue windows together (make them stick to other windows), possibly as an extension to tabbing but without sharing window area.
The windows glued this way should be raised and lowered together, should be moved and resized together: for example two windows glued on a vertical border will have the same height and resizing the height will affect both.

As possible uses I see: gimp (pre 2.7), terminals, terminal+editor, chat programs

dupe of request #83, gimp btw. meanwhile as a single-window mode ;-)
