Workshop Devkit: Add a miscellaneous comment box to attack blueprints#65

Requesting to add a miscellaneous comment box to attack blueprints so devs can record information relevant to the attack for later reference through the R2 Mod Kit. In R1 workshop, a dev could add comments to their attack scripts highlighting where they got frame data and hitbox data from, why they implemented things in a certain way, how windows functioned, changes to the attack in patch notes, etc.

It would also help collabing devs see these notes and share notes on an attack by attack basis without having a seperate document outside the editor.
