Mob Grinding Utils

New Content Additions
* Entity Spawner - uses a Mob Egg and XP Jelly Babies to spawn Mobs. Has Custom Area Upgrades and takes Speed Upgrades.
* Delightful Dirt - Spawns passive mobs. Snow caps if exposed to Sky during Night-time. Light of 10 or more allows Spawns.

Will cover with tall grass or flowers randomly (This will prevent spawning - so mow the lawn).
* Nutritious Chicken Feed Item - Feed to Chickens for a Golden Egg (to create Delightful Dirt)
* Golden Egg Item - Creates a 5x5 area of Delightful Dirt, When used on Dirt, Grass, Mycelium, or Farmland.
* Monocle Item - NYI fully - so just a spiffy head piece atm.

New QOL Features
XP Jelly Baby - Whole Stacks can now be consumed whilst sneaking.
Tool tips have been re-orgnised a bit in code.
Renamed Speed upgrades - Now they are also used in the Entity Spawner.

Fixes
* XP Solidifier fuel slot should only work with and accept XP Jelly Babies.
* Improved Dreadful Dirt spawning for mob collision checks to prevent mobs escaping through blocks.

Curseforge decriptions and recipes to follow soon - for now JEI will help with recipes.
