Add support for named potion types and enchantments.
In this commit, the ItemParser's behavior changes from one that requires or encourages numeric IDs for everything to one that discourages it by logging a warning that suggests using a string instead of a numeric value. While this doesn't actually make things that much better for updating to Minecraft 1.13, the "ID nagging" hopefully increases awareness about the upcoming breaking changes. Fixes #382
