Java Edition 1.12-pre6

1.12-pre6 is the sixth pre-release for 1.12.

Changes

 * Optimized recipe book & creative inventory searching a lot, especially when using mods
 * Made a bunch of text translatable, where previously they were hardcoded English
 * Optimized chunk loading, a previous pre-release slowed it down :(
 * Added the ability to see credits by clicking the copyright text in the title screen
 * Technical: Skipped functions (when the conditional fails) is now considered a failure (for example in command blocks)
 * Technical: Tab-completing command names in command blocks will no longer add a / prefix.
