Add config for gluttony charm so users can add/block additional food items.

[iTitus]

Closes #223

This also updates Forge so that I could test this with the newest Mekanism.

The config looks like this per default:

[gluttonyCharm]
	#The registry names of food items that the Gluttony Charm should NOT consider valid food.
	blockedFoodItems = []
	#The registry names of additional items that the Gluttony Charm should consider valid food.
	additionalFoodItems = ["mekanism:canteen"]

Sorry about the indentation in the build.gradle. It is not consistent across the file and IntelliJ gets confused.

This is also a start for #213

Thanks, I spoke to the mek devs about a way to get official support working but I forgot what we said. Planning to reach out again in a bit. I do like the config option though.

Ultimately decided to fix this by just allowing drinks to be used, this is based on the use action of the item. So potions are also fixed. b6a4af3
