correction for GeoServer
Merge branch 'KML_WMS_XYZ_overlays'
in KML loader: add description parser for "equation-like" data, and use this data as fallback, if name/place cant be loaded otherwise
Merge branch 'origin/master'
BugFix: only try to load time-spans if there were non from the tabular data, and only add them if they are "valid"
