Mekanism JEI Fix

NOTE: As of 9.6.x+ of Mekanism this is no longer needed, and in fact should probably not be used.

This is a small coremod that fixes Mekanism's JEI rendering for gasses not obeying their tint color. (Corresponding to the first commit of this pull).

I made this mainly for use in my own mod pack so that I can create custom fluid's with ContentTweaker and then use MekaTweaker to create gas variants, without having to manually color in the textures. (What I have done up to this point). Though this issue is not just limited to custom gasses as the built in Mekanism ore slurries do not display correctly either in JEI. (As shown in the images tab with osmium slurry to clean osmium slurry.)
