aa302c237d Use standard formula for CDB_ZoomFromScale
postgis-vt-util comes with a standard formula for zoom from
scaleDenominator, and this is well tested. This also fixes the
function throwing an error on NULL input.

9526f0448f Fix bug in feature density recursive query
If the table had x and/or y columns they were picked by an inner
select instead of the recursive arguments.
Fixes #256

3399f2b9a5 Fix max overviews level usage
Note that _CDB_Feature_Density_Ref_Z_Strategy returns the first
level for which overviews should not be used, and that in some
cases _CDB_Feature_Density should look beyond the max level to
compute a feature density estimate.

803b3671d0 Fixes for feature density computation
* The initial iteration of the recursive feature density query shouldn't
  start beyond the maximum level
* Correct off-by-one limit the rest of iterations

This only generates the stats if no stats are available for a table.
This doesn't warrant that the stats are up to date or accurate.

417cbe7902 Fix category columns aggregation in overviews
Overviews are created in cascade, each one from the inmediate
lower level, but the stats to decide if a column is a category
should be taken always from the base table.

1b0f77aa96 Always retain single-valued aggregated texts
This makes columns which have the same value in a group to be aggregated
maintain that value (rather than replacing it by the multiple-value
indicator *) whatever the group value is. (Previously this happend
only for small groups)

tiler only, but that makes the column hard to access from the editor.
