okan 3207d6dcc9 Since we use IconicState as our hidden state, check for the hidden flag
and unmanage the client if we're not hidden (basically if NormalState)
during an UnmapNotify event.

Resolves an issue with mplayer going fullscreen while not using NetWM
hints; behaviour regression reported by Ido Admon.
