RPGMaker Trans v4.2 Beta Released

As stated, it's been released. This fixes the following:

• a bug due to the fact that Ruby defines some global variables which do not conform to the normal rules for variable naming, thus causing Ruby parser to enter a slightly less than infinite loop.
• a bug due to not testing patching XP games properly where for each dialogue, the first line of the dialogue was missing

This is a beta due to me making some quite invasive changes for the 2nd fix, and me not having enough time to properly test this version.
