Provide an option to the user to constrain searches for spatial table… 
…s not

in the geometry_columns table to just those in the public schema. For some
databases which have a lot of ancillary stuff out of the public schema this
can significantly reduce the time that qgis takes to produce the list of 
tables to load.  

Also tidy up the cause of some console warning messages about unknown
geometry types that happened when a spatial table not in the geometry_columns
table had no non-null geometries in it.
