#3133: Allow for --display to reach gtk initialization

--------------------------+-------------------------------------------------
 gtk provides the handling of the standard X --display option, but pidgin's
 command line parsing is done before gtk_init_check, and --display is
 reject.
 This small patch adds --display as an acceptable command line switch, so
 that gtk can then handle it.
