"Replace Missing Units" pop-ups in WorldBuilder

[ViTeXFTW]

Problem

When opening a map in WB that has custom units (map.ini), a pop-up will prompt the user to replace that object with another. This can be annoying when there are 100+ (even 10+) objects which are custom.

Solutions

1. Add a button to the pop-up that (in principle) cancels all the pop-ups and just remove the objects from the map (By pressing cancel on the pop-up, this is essentially what happens, just per object).

2. Add a feature that also looks for a map.ini (solo.ini) when opening a map and adding relevant entries.
