the inferno forge now stops running when it runs out of ember
the jei display of mixing recipes now displays all 4 input slots
added a gauge display tag for addons that add their own gauge items
buckets can now take steam from boilers, since it was impossible to get steam in a bucket otherwise

fixed a crash when firing a beam cannon at an ember relay
fixed the diffraction barrel not copying the color of the projectile onto the smaller projectiles
