* gdbtk.c (get_register): Support for printing raw formats.

Browse Source 
* gdbtk.tcl: Add hint for using debug_interface.
	(center_window, add_breakpoint_frame, delete_breakpoint_frame):
	Enclose arg in braces for consistency.
	(create_registers_window, populate_reg_window, update_registers):
	Major rewrite to support displaying multiple formats in the register window.
	(init_reg_info): New function.
	(recompute_reg_display_list):  Reset reg_display_list, start
	register display lines at line 2.
