Heater functionality:

- Heated Mixing: Mixing can now require the player to heat the basin (with either the usual fan heaters for a heat level of 1 or the blaze heater for higher heat levels)
- Made mixing brass ingots from copper and zinc ingots require heating (as example)
- added the blaze heater to valid fan heaters
- added TE renderer for fan heater to display a blaze head always facing the player
- added fueling of blaze heater with furnace fuel (onUse event, not with inventory to challenge the automation. To be discussed.)

todo:
- add heat requirement display to JEI
- better item model for blaze heater
- new special fuel for higher heat levels
- fan stoking
