Elijah Newren 9fdd3d165d Fix accidental overzealous focus holding by the terminal introduced by the 
2006-01-15  Elijah Newren  <newren@gmail.com>

	Fix accidental overzealous focus holding by the terminal
	introduced by the original patch in bug 326159.  Windows launched
	from panel icons, the panel menu, or global keybindings should get
	focus now.  #326159.

	* src/display.c (meta_display_open, event_callback):
	* src/display.h (struct MetaDisplay):
	* src/keybindings.c (process_event):
	* src/window.c (meta_window_set_user_time):
	Add a new allow_terminal_deactivation field to MetaDisplay and use
	it to track whether the user's last action was interaction with
	the terminal or some outside action (global keybinding, clicking
	on a dock, etc.) likely to launch a new window.

	* src/window.c (window_state_on_map):
	Allow the focus switch from a terminal to something else if
	allow_terminal_deactiviation is true.

	* src/keybindings.c (handle_panel_keybinding):
	Remove some unneeded code.
