windows. Skype works!

Move atom name query in propertynotify to a separate function.

Rename active_wm() to enable_wm() since the purpose of the function is
to enable X window management.  The error check is now done within the
function. Like before, return 0 on success; 1 on failure.

New debug type: SWM_D_INIT

More type casting.
