Raba split for OpenStreetMap import

These scripts prepare the RABA-KGZ source shapefile into form suitable for import into OpenStreetMap, by performing these actions:

Re-project source from Gauss-Krueger/D48 into EPSG:4326 (aka ETRS89, WGS84) using GeoCoordinateConverter
Split the reprojected shapefile into smaller 2x3 km sections as defined in split grid, manage-able for import
Dissolve (join) neighboring polygons of same type into one
Tag the splits with OpenStreetMap tags directly as defined in mapping table.
Hack the produced shapefile to include 11-character fieldname and special character (namely "source:date" and "raba:id" OSM tags)
Zip all the parts of shapefile for import using JOSM with opengeodata plugin
Optional: use JOSM remote control via dedicated raba.openstreetmap.si website (source in git) to perform import

Source shapefile from http://rkg.gov.si/GERK/, eg. RABA_2015_10_31.RAR (600 MB)
GeoCoordinateConverter (http://geocoordinateconverter.tk) was needed to convert old national D48 Gauss Krueger source before it was available in D96 Traverse Mercator
ogr2ogr from GDAL suite
bbe Binary block editor

Run the main script:
```
./prepareSource.sh
```
Wait an hour for the script to finish - for best results just put it in cron and enjoy .
