* settings-dialogs/Makefile.am,

	  settings-dialogs/shortcut-dialog.{c,h}: Add (almost) the same dialog for
	  entering shortcuts as we have in xfce4-settings.
	* settings-dialogs/xfwm4-settings.c: Implement the first part of the xfwm4
	  keyboard shortcuts: Disable themes support, make shortcuts editable,
	  implement the "reset to defaults" feature, handle 'property-changed'
	  signal emitted by xfconf and allow for interactive resolving of
	  conflicts. Still missing: hard-coded default shorcuts and the actual X
	  event monitor for all shortcuts. \n 	* POTFILES.in: Add shortcut-dialog.c.
	* *.po, xfwm4.pot: Merge new strings.
