fix crash in dirtomon() when selmon is disabled
closemon() now updates selmon if needed
use just one loop in outputmgrapplyortest()
we do the magic in updatemons()
move focus and clients off disabled monitors
update comment about exclusive focus in focusclient()
stop trying resize clients during commitnotify()
instead resize them in configurex11()
allow unmanaged clients (like dzen or dmenu) to have keyboard focus
use `/* */` for comments in applybounds()
fix bad indentation in createpointer()
rename dragicondestroy() -> destroydragicon()
to match the rest of the code
rename LyrNoFocus -> LyrDragIcon
correctly handle cursor motion when button is held (for layer surfaces)
fix drag and drop not working
this fixes another issue where the cursor doesn't change when selecting text
but there is still an issue about not changing border color of clients during
dnd operations
