[Therion] Shape files import comes up in the wrong location in QGIS

[Martin Budaj]

Hi,

georeferencing data for shapefiles are currently not supported for
OSGB:xx coordinate systems, but the fix is planned.

For now, just select utm30 as an output coordinate system (in the
thconfig_plan use the line
   cs utm30
before exporting shp maps).

Cheers
Martin
