* gdbtk.tcl (add_breakpoint_frame): Add more fields.

* (create_file_win create_asm_win build_framework):  Create null
	bindings for meta keys to keep window from dropping down to
	insertion point when meta is pressed by itself.  New bindings:
	   Up/Down - Scroll up/down one line at a time
	   Next/Prior - Scroll up/down one page at a time
	   Home/End - Warp to current pc/end of file
	* (build_framework):  Turn on breakpoint menu.
	* (create_command_window):  Implement tab completion.  Add binding
	for ^C to stop target.
