1f01ecae30 Exclude overviews from user data size 
Fixes #261

Some internal functions from the Overviews module
have been moved to a separate file because they're now
used from Quaota function.

0b3ad5e569 Limit the maximum zoom level 
Avoid returning zoom levels greater than the maximum
'safe' level. For a zero denominator (which would imply
and infinite zoom level) return the maximum level too.

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.

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

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)
