This is rather ironic...

My VERY FIRST PR, I used it to make ghost chat be bold, instead of using viewers() to figure out
what ghosts could see the mob, I used get_mob_in_view() which sounded pretty descriptive.

Unfortunately for me it was one of the most CPU intensive ways of determining who could view the speaker for this.

So yeah, removing the second get_mobs_in_view and replacing it with viewers()

Yes this code has been in since Oct/Nov time frame :(

Further optimizations, no need to loop through items with multiple istype checks
