Zero damage text

In RBY, there are extremely minor situations where zero damage can be dealt. These usually involve quad resists and profound level differences.

To quote the disassembly:
; this only occurs if a move that would do 2 or 3 damage is 0.25x effective against the target
However, Psywave is also capable of this.

Thus, a new case has been added for when this occurs, which is triggered through a new WRAM entry. Easiest way to do it without having to restructure how misses are handled.

This is overall minor, but it'll probably make at least one person laugh, and that's all I need.
