Equipment Check Event Command

I believe two of them that we added were status-related: one to check for status on a certain character (this is really needed to properly fix a few bugs) and one to set/clear status on a certain character.

I did take my inspiration from PB to code an event command that can check if a certain status is set on the party leader and branch to an event subroutine if it's the case. It was one of my first ASM coding. Your work and the work of all the PB team has been an inspiration for me and I'm sure other folks as well.
