Various Oddities

Additions

• Added the Paralysis status effect, which prevents mobs from moving and shunts players to a menu screen whilst active. This is not currently used by any creature or effect, only through the /effect command, but is one of the common effects that creature types can grant immunity to.
• Abilities can now be given custom names through NBT
• Several new abilities, including Tremorsense, Water Walking, and natural health regeneration
• Fully implemented the favourite ability keybindings and activated ability menu, with client-side control for where and how they display. Open the menu (default key: M) to see all passive abilities (on the right-hand side) and a scrollable wheel of activated abilities. Click the star icon on an ability to add it to the first empty slot in the favourites, or click on the inner section of the wheel to activate it (if currently possible, the ability will be black if not). Clicking anywhere else closes the screen, as does clicking the menu key again (or releasing it, depending on client config).

Changes

• Many effects formerly applied by the creature types system are now done through abilities bestowed by the types, though some remain in the types system for the time being (flight for instance will be an ability in future).
• Custom creature types are now stored in the creature entity instead of world save data, this means that now individual non-player mobs can have custom types applied to them, but has the unfortunate side effect that custom types applied to players in existing worlds will no longer function unless re-applied.
• Initial implementation of species, a collected branch of both creature types and abilities that will be used in future to allow players to severely customise their gameplay without the necessity of admin commands. The system isn't 100% operational in this version, but the functions are available for testing out.
