Upgrade jvectormap, regenerate map

Upgrades jVectorMap to 2.0.0, fixes #117

Corrected shapefile (it didn't specify a coordinate system. Loaded with qgis and saved with WGS84) and regenerated tdwg-level-2 map. Now regions work and markers appear in correct spots.

Have not changed region names (see #110)  - if they should be changed, best to do in the shapefile, which feeds the database and the map.
