Move the GTK+ implementations of various UI utilities out of "util.c"

into "gtk/ui_util.c", and move the declarations of those UI utilities
out of "util.h" into "ui_util.h".  (The header file is in the top-level
directory, rather than the "gtk" directory, because it declares
window-system-independent interfaces to routines with
window-system-dependent implementations.)

Add to "gtk/ui_util.c" a routine to set the window and icon title.

Use that routine to make the title of an Ethereal top-level window be

	{filename} - Ethereal

if there's a capture open, and have "{filename}" be "<capture>" if it's
a temporary capture file.
