Side-Only Types of Fixes and Minor Improvements

Prevents server crashes from a part of the bullet homing effect (fixing #201 and possibly #197), as well
as cauldron particle effect crashes.
The cauldron now only takes what it can use from item stacks thrown into it (also meaning that if multiple redstone are thrown in, it recognizes more than the addition of just one).
I also commented-out the line adding unused tooltips for the empty and standard magazines.
