v1.7: Original Trilogy fixes and actually cool additions

Feels good to be back in gamedev mode after SAGE. Anyways, this is the first of a few QOL updates I'll be doing for the current classic pack games, focusing on the original trilogy. A few critical bugs and things were found and squashed. Two REALLY cool extra things have also been added:

1 (2006) now has a toggleable soundtrack option! You can play with the 2006 soundtrack, or the Ultimate Edition soundtrack made by philRaco.

3 now has a right stick quick select wheel for gamepad users. By using the right analog stick, you can quickly select between Scruffy's three different forms.

Next updates I'd like to do will focus on Rides Again and 1 Remastered. I need to port Rides Again to GMS1.4 and add gamepad controls, and as for 1 Remastered, I'd like to give it all the extra new features that the original trilogy got. I am also planning which other games will be inducted into the classic pack next, so stay tuned!
