Subject: [PATCH] Added dumpnodes mod  - Added dumpnodes mod, creating
 /dumpnodes command which can be used by admins    to drop the nodenames and
 top tiles' images for every node on the server in    the aim of beginning a
 process designed to generate automatically the    colors.txt file needed by
 minetestmapper
