[xmonad] announce: XMonad.Layout.Monitor

[Roman Cheplyaka]

XMonad.Layout.Monitor is module for managing 'monitor' windows. Monitor
windows are like dock windows, but they are placed above other windows.
For example, see screenshot[1]. 
'Monitor' is layout modifier which shows monitor window above the tiled
windows of current layout.
Its features are:
- works with unmanaged windows ( => it's trivial to get monitor on all
  workspaces, plus monitor never gets focus)
- toggling visibility with a keybinding
- it's possible to have several monitors and toggle them independently
  (using nested modifiers)

Due to stacking algorithm of xmonad, it isn't currently possible to show
monitor above floating windows.

For details, please see the docs. Comments are welcome.
