[TF2/ANY?] Resolve workshop map display names.

[Heapons]

That is to say: workshop/<mapname>.ugc123456789 → <mapname>.

Here are the main reasons why this would be useful:

• Not having to maintain an extra workshop subfolder in waypoints/<modname>/.
• Download and setup third-party waypoints more easily without having to manually rename the waypoint file to match with its workshop counterpart.
• Server owners who use Rafradek's workshop fix.
• Server owners who prefer to move workshop maps to FastDL.

It would make setting up waypoints more convenient and less redundant. In the meantime, I've been using #46 as a workaround to load waypoints that aren't specifically in workshop.
