Include map size in thread title & sub-forum for map scripts created

When posting a new pre-made map, please be sure to include to the map size in the thread title. This can be either exact dimensions like 100x50, or descriptions like Small, Medium, Large, and Huge, or both.

I will edit the exisiting map thread titles to incldue this info.

A new sub-forum has been created for the map scipts. It's a sub-foruim for now since there are not many of them yet.
