Menu text stroke

Many NPC menus have display issues with the various level backgrounds and we've been modifying all of them manually to attempt to solve the contrast issue.

This change creates a black text stoke around white text menu items for optimal legibility on top of any background. Therefore, I have removed the menu text colour options and changes we have done previously for other NPCs as they are no longer necessary.
