The "Take a Shot for Every Cauldron Refactor" update

• remove the stone cauldron (apologies, to be reimpl'd in another mod)
• abstractify cauldron behaviors a lot, change CauldronUtils into Cauldron interface
• update to 19w14a (still compatible with 13b)

Stone Cauldron

• create a Stone Cauldron to move non-water cauldron behaviors to (so we don't have to write as many hacky injections into the vanilla cauldron)

Clean-up

• comment out sample code for recipe nullification (make sure to delete the recipe json in the cotton (generated) global resource pack so that you can make crafting tables again)
• comment out sample code for cauldron behavior (will likely go into cotton tweaks)

Recipe nullification

• add a system to eradicate existing recipes without getting tons of console spam
• fix a production-environment issue where the refmap is saved under the wrong name

Yet Another Cauldron Fix

• change the property stored in CauldronUtils to prevent crashes
• add a method to remove a bottle's worth of fluid from a cauldron

Cauldron fix

• fix empty cauldrons resetting worlds

Cauldron behavior: parts 1 and 2

• add a library for cauldron behaviors (interactions between a cauldron's fluid and an item like getting water bottles or making obsidian)
• add support for cauldrons to hold either water or lava (support for non-vanilla fluids coming soon)

0.0.8+19w13b: add Identifier util

• add utility class for transforming Identifiers, courtesy of @Daomephsta

0.0.7+19w12a: Add common tags

• add raw meat, cooked meat, mushroom, pressure plate, carpet, terracotta, glass block, and glass pane item tags
• add config option for auto-importing modded items to common tags (off by default)

First public release

Cotton is ready enough for a public release. More will be added as needed.
