Default to not displaying the fake light around mercs (#86)

* Remove option to disable 'Mercs Lights during Movement"

This might've cost someone some frames in 1999, but today even a 10
year old smartphone can probably run with this turned on at 1080p without
dropping a sweat

This does not remove the menu option which I plan to replace with
'Highlight Mercs' which was hidden for some reason.

'Merc Lights during Movement' is a noop now tho

* Replace 'Merc Lights during movement' with 'Highlight Mercs'

as title

* Make 'Merc Highlights' default to false

"Wtf why am I glowing?" well your problems are over
