Add glow argument to find command.

Add a glow argument to the find command to glow the found entity/entities.
Discussion points:

• Time for glow
• Color of glow
  Should these be changeable by the player?

For anyone wondering why:

• Easily locate the entities
• When using effect to glow all entities you want, it doesn't apply to those outside of render distance, with keep searching this is easier

Isn't this the same as /cglow entities?
