(svn r2597) Feature: [string system] Support cases.
- Cases are used to change a string, such as Coal Mine, depending on the surrounding context. - Cases are defined like "STR_4802_COAL_MINE.ack :Coala Mina" - All cases need to be listed on the top of the file like this "##case ack" - When using the string, type {STRING.ack} to choose the "ack" version of Coal mine. - Also combined the strgen arrays into a struct, and fixed a bug with SetXY.
