Huge updates for Hartshire and Xenon (R3creat3)

Imports may be incorrect, probably not.
LIST OF FIXES:
- Disable Enderpearl damage on Xenon, stop abusing the 3-second-invincibility glitch
- Add EXP bottles to Xenon
- Actually make the Light Blue Dye get removed on use
- Actually make the Hartshire grapple hook work
- More, I probably forgot or didnt add more.
