New Features:
- Spanish language added (Translation by PibeChileno)

- "Custom Language" added. This is just english, but editting this may make
it easier for some people to add a their language without it getting overwritten

- Languages.yml now updates similiar to config.yml in the fact that your edits are saved on updates.

- You are now able to add up to a total of 12 languages that will be displayed in the config for players to choose from.
To do this, simply copy and paste any of the sections in langauges.yml (make a duplicate), rename the language ID to whatever you like, then make edits. If you are only adding one language, I'd recommend editing the "custom" language as it is less bug prone.

- Percentage completion of languages is now calculated by the plugin instead of estimated be me. It's calculation is based on how many strings differ from the english verison of the string.

Bug Fixes:
- Fishing up Junk and natural treasure (Tiers -1 and 0) now give EXP as they should
