Subject: patch: elit

elit is an inversion of the default tiling layout with the following
characteristics:

    - master area is on the right
    - master windows are taken from the bottom of the stack (nmaster of
      them)
    - new clients spawn on the top of the stack and therefore appear at
      the top of the slave stacking area on the left
    - mfact controls the middle division point (motion is consistent
      with default layout)

In effect, elit will keep specific client windows pinned in place on the
right, allowing the use of a dynamic stack on the left.  I've found this
useful to use on a secondary monitor for opening and closing short-lived
terminals without affecting the geometry of a web browser window, which
can reserve the full height of the display.
