SOC sanitizing

Hopefully fixes the crash reported in this post here: Crash Reports (SIGSEGVs, etc) #132 The crash occurred because of the game iterating over a line of text from a "Frame" aka "State" SOC block for seemingly no purpose whatsoever: if it had no '=' or a new line char on the end (such as when you set the Action for a state), it presumably then went outside the buffer thus causing access violations. Fun.
