 [1.5.x] Fixed geojson detection with Spatialite

 This is a partial backport of commit eb9430fc4be1. Without this,
 geojson support is never detected with Spatialite.

Comment (by claudep):

 OK, now I see the bug, which has been fixed in master by commit
 [eb9430fc4be1]. It was unfortunately a bit late to enter the 1.5 branch. I
 will try to make a more limited patch for the stable branch. Could you
 test the following patch to see if it resolves your issue?

Comment (by burton449geo@…):

 In the django project shell: print(connection.ops.spatial_version())
 returns 3.0.1 and connection.ops.spatialite_version_tuple() returns
 (u'3.0.1', 3,0,1)

 In spatialite prompt: SELECT spatialite_version(); returns 4.0.0

 There is no error on those results, it was done on the same spatilatie db
 defined in settings.py

Comment (by claudep):

 Oh, sorry, `spatial_version` is a cached property in master, but it is a
 method in 1.5. So the last snippet line should read
 {{{print(connection.ops.spatial_version())}}}. Here is the code:
 
https://github.com/django/django/blob/stable/1.5.x/django/contrib/gis/db/backends/spatialite/operations.py#L246

 Basically, this executes the SQL query `SELECT spatialite_version();` (you
 can also try it at the spatialite prompt).
 It would also be interesting to get the result of
 `connection.ops.spatialite_version_tuple()`.

Comment (by burton449geo@…):

 The return is None. I have made a test and re-creating a new spatialite db
 from spatialite_gui v.4.0, but it still returned None. When I use a
 PostGIS settings it returns 2.0.3. Do you know what could be the meaning?

 Could you try this snippet inside your project:
 {{{
 $ python manage.py shell
 >>> from django.db import connection
 >>> print(connection.ops.spatial_version)
 }}}
 It may be that your Django instance does not use the expected Spatialite
 installation.

 geojson support for Spatialite has been added in Django 1.5. I'll add the
 missing notice to the docs.
