Better Statistics Screen

General changelogs:

• The technical world info in general stats will now only show up when DEBUG_MODE is enabled.
• Added a separate stats tab for "Credits" and "Translators". The mod will now link to translators GitHub profiles.

The following changes were made to allow people to to incorporate the /stats command into their data-packs and custom maps:

• Improved the /stats command output mechanics
  • clear and edit will now output an integer representing the number of affected players.
  • The output number will be -1 if a command error or a syntax error takes place, and the command fails to execute.
• Added query. Useful for map-makers.
  • query will now output an integer representing the current stat value for a given stat of a given player.

Note that the same technical changes were made to the /badges command for the embedded tcdcommons API mod.
