Updated Gradle wrapper to 1.11
Some stuff, you know.

Worked on Fortune Coin.
- Changed ‘on’ state overlay. Subtle, but still extremely noticeable.
Also looks cool.
- Messed around with the particles that spawn on item pickup via
Fortune Coin.

- Made the Midas Touchstone’s glow conditional on it having Glowstone
in it.
Assets just got new names.

- I changed the assets to match the new variable names, and
fit_in_with_the_vanilla_naming_convention.

- Changed Salamander’s Eye and Wraith’s Eye textures to use animations,
instead of a TickHandler.

- Sadly, I don’t know enough German/Russian to keep the localizations
up to date. So, if you can translate those, it would be great.
