Additional SM bugs(hopefully) quashed
space2tab Supermatter (Only changed lines 84 - 90)

Suppermatter entities in crates were running process() while inside crates and failing the turf istype check, deleting their process and
in an odd case deleting the actual entity.

Did a null check on loc and if so stop processing all together.

If istype check failes (it's not on turf, but in a crate) we just return so that when it exits the crate it can start processing again, but don't want to process while in the crate.

Also fixed some typos in datums/supplypacks.dm
