1) Added another convenience wrapper that allows to select an X() action
from a given list.
2) Implemented the option to change the position of the selection diamond.
(Re-recorded from Bluetile repo, rebased to current darcs)
This patch generalizes Actions.GridSelect to work for arbitrary (String,a)-lists. The changes break configurations that used `gridSelect' directly, which is now named gridSelectWindow. As an example for uses of the GridSelect-UI, I included a function to spawn an application from a list of commands(`spawnSelected').
* handle/eventLoop carried the display and the drawing window as
parameters. The display is available from the embedded X monad, the
drawing windows was added.
* updateWindows now takes a list of windows to
update. updateAllWindows updates all windows.
* only the windows that are modified by key movements are redrawn
now. This means less flickering.
