Title: A simple geojson importer for Gdms.

This adds a simple GeoJson importer into Gdms.

Main features are:
* entirely stream-based: never hold in memory more than a Gdms row,
* quick metadata parsing: parses the metadata on a call to ```open()``` without actually parsing the content,
* support for all geometry types,
* support for feature attributes (integers, doubles, strings, booleans)

It uses the Jackson library, which is one of the best out there, and is very lightweight (jar is 190K).

There are still some more work to be done:
* add support for CRS
* be less strict as to the geojson format (currently we suppose the file is well-formed, and abort as soon as something is weird)

But I would like to also have a working exporter before getting there.
