* soldiers now drop their upgrade items (when unused / those have infinite uses)
 * (re-)added ghast tear upgrade (for some reason it was under enchancement upgrades and not registered!?)
 * added bunny recipe
 * fixed mounts taking damage from projectiles thrown by allied soldiers
 * soldiers won't use slime and redstone at the same time anymore
 * soldiers will use blaze powder before they try to use slime/redstone
