gis: Fixed 6414, and applied DRY to spatial backend internals. Changes include:

(1) Support for distance calculations on geometry fields with geodetic coordinate systems (e.g., WGS84, the default).
(2) The get_db_prep_save and get_db_prep_lookup have been moved from the spatial backends to common implementations in GeometryField.
(3) Simplified SQL construction for GeoQuerySet methods.
(4) SpatialBackend now contains all spatial backend dependent settings.

    2  The Oracle spatial database backend module.

    4  Please note that WKT support is broken on the XE version, and thus 
    5  this backend will not work on such platforms.  Specifically, XE lacks  
    6  support for an internal JVM, and Java libraries are required to use  
    7  the WKT constructors.
