Changed running and walking anims, all fixed! God be praised!

Steam user referenced some errors in .lua code. I have fixed them in this update, and if any other bugs are reported, I will not hesitate to fix them. Any bugs for others are bugs for me (be aware that some bugs MIGHT be from your end).

Reinserted 'sillyrun' animation, if it doesn't work I will resort to ACT_RUN.

Inserted ACT_JUMP to replace original anim. Reloaded model with new anim constraints.

Thank you, Father in heaven.
