Composter improvements

[happyburger23]

• Hoppers should be able to insert plants into the composter
• Particles that appear when items are inserted should be at the top of the composter as it is for vanilla MC

EDIT: Comparators should also read the composter's fullness level, also vanilla MC

is the hopper thing from vanilla

Yeah in vanilla Hoppers can interact with Composters, to the point that Hoppers literally lag LESS if they have a Composter above them, but I am pretty sure you need to mixin/asm something into the Hopper itself to make it work unless you add a TileEntity to the Composter.
