Support for OGC GeoPackage (GPKG) format for Vector feature up/download

[GoogleCodeExporter]

GeoPackage (GPKG), see http://www.geopackage.org is the upcoming OGC standard 
for storing and exchanging both vector and raster (for now tiles) information 
in a single file. The file-format is based on SQLite. 
GPKG is touted as "The Shapefile of the Future":

Ongoing implementation of the GPKG can be found in a.o. GDAL OGR (1.11 dev 
branch): 
http://www.gdal.org/ogr/drv_geopackage.html (work by Paul Ramsey). 

As Heron already support up/download via heron.cgi and heron.cgi is using 
ogr2ogr (from GDAL/OGR) already, it would be quite trivial to add support for 
GPKG. The requirement is to install the latest GitHub version of GDAL by 
compiling from source or using prefab downloads. 

Only some small changes are required in Heron:

- one/two-line addition to heron.cgi to recognize .gpkg
- extend config for some examples for FeaturePanel and Drawing and apps

Most examples involving up/download now include GeoPackage. Probably Heron is 
the first viewer now to support GeoPackage! See the showcase app KadViewer for 
examples, e.g. download in drawing:

See also some general notes on GeoPackage, from my presentation, that triggered 
including GPKG in Heron.

Note: to use in your environment you need to install the very latest dev 
version of GDAL (v1,11dev)!!!
