Add "has corrected coordinates" to geocaching import filters.

There are several filters for importing nearest geocaches (for premium members). Could "has corrected coordinates" be added as a filter?

Rationale: the live map only shows caches in range of the current window (zoom) ; for caches with corrected coordinates, that means the ORIGINAL location. When zooming in on the CORRECTED location, they disappear from the map, as that's typically out of range. The solution is to download solved mysteries to locus, so they stay on the map. Therefore, when using the live map, I want to download only caches with corrected coordinates.
