Javier Goizueta a067cc7da1 Generate stats used to identify category columns in overviews if needed 
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.

Javier Goizueta 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.

Javier Goizueta 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)

Javier Goizueta 45f063d469 Aggregate small number of text items in overviews 
Instead of nulling text fields for non-singleton aggregated records
concatenate distinct text values when they're few (5 or less).

Javier Goizueta c595e45c11 Add _vovw_count columnt to tables for which overviews are created 
Initially we planned to add this column to the queries sent to the
tiler only, but that makes the column hard to access from the editor.

Carla Iriberri f96163265b Fix bug for tables without geom or with no potential overviews 
If the table doesn't have geometries but the createoverviews function is
called, the current geometry type checks won't work because "null" will
not give a boolean value in the type comparisons.

Also, if the createoverviews function is called over a simple table with
would not require overviews according to the strategies it is handled
correctly.
