Crafting Station: JEI Edition

- Updated to latest JEI, to fix most cases where the + icon was not appearing.

Due to a JEI change, there are now some cases where you will not be able to + in resources - any slot which is not "modifiable" will not work. A good example of this is the output slot of a furnace, where the game will let you withdraw items but not insert. JEI blocks interactions with these slots now, so a fix is out of my capability.

This patch however catches those cases, and just ignores those slots. Previously the mod was falling over if it encountered one of those slots, and ignored all slots as a result, so this is still an improvement!

I've also added a small warning icon to the corner of a tab which has a problem slot in so you can tell where problems may be. JEI will still work fine with these present, it just can't see the relevant items. For example, say you had a furnace neighboring your crafting station which has iron ore smelting - you won't be able to quick-move the iron ingots in by pressing +.
