Issue description

If you pass Flay Mind something that isn't an entity in the place where it's expecting an entity, the function shown below causes a mishap:

However, entity.mob is not a valid lang key, and thus you get a mishap message that looks something like this:

This could be fixed in a variety of ways. A new lang entry could be added for entity.mob, but I don't think this is actually necessary. There's already one for entity.living, so the getMob() function could just be changed to use that instead.

Alternatively, getMob() could be removed entirely (it's only used for OpBrainsweep) and replaced with the nearly identical getLivingEntityButNotArmorStand() function which is currently used in OpPotionEffect. This would, however, require changing various bits of brainsweep-related code to expect a LivingEntity rather than a Mob.

Steps to reproduce

1. Attempt to cast Flay Mind with something other than an entity as the first argument
2. Observe broken mishap message
3. Observe that the mishap.invalid_value.class.entity section of the lang file doesn't have an entry for mob
