Add ST_GeomFromGeoJSON

[colivier]

Same behaviour than other import functions, but related to GeoJSON.

Surely need to use a parser to do the job (LEX/YACC for example)

Kashif -- can you attach a diff to this ticket to make it easier for us to look at.

[pramsey]

Yes, a diff against current trunk and I'll integrate/apply it.

[kashif]

I have attached a patch to the current svn for testing.

[pramsey]

Super! On it.
