introduce a new 'freeze' flag (CMS-f by default) which may be applied to

any window, after which all move/resize requests will be ignored,
essentially freezing the window in place.

there's a possibility to merge this with the 'ignore' concept, pending
on how ignore+freeze should behave (really more ewmh stuff), but punting
for now since ponies are on the line.

requested and tested by thib at k2k11 with ponies, unicorns and rainbows.
