Fix:	GTK002

Problem:
	GTK interfaces attempts to allocate writeable colours. This causes
	problems on many displays where colours are in short supply. In
	any event, the interface never needs to change the colours and so
	read-only (shareable) colours are just as acceptable.

Compatible with:
	GTK+ NetHack v 1.1.5
	Slash'EM 0.0.6E0F2
