## About The Pull Request

1. **Fixes Toy Sword Icon and Rewrites Procs to use E-Sword.**

## Why It's Good For The Game

1. _The toy sword off icon was broken, so I looked into it and it's
using an outdated sprite name. So I changed it, but then I looked over
the proc, and I realized it would be more fun if the toy sword had some
of the real one's traits - like the rainbow thing if you multitool it,
and alt-click color change support. So I started adding those, but I
didn't like putting all of it in one attack_self proc, so I've instead
just cloned over the procs from the esword and adjusted them to suit the
toy instead!_

<!-- You can use multiple of the same prefix (they're only used for the
