more col data_type/profile cmbos + tmp bypass for Pg 'array' type - refs #55

Added more known column data_types with mappings to column profiles
(mainly based on new types seen in Postgres sample databases) including
temp settings to disable postgres-specific types for which we do not yet
have proper support, including 'array' columns (e.g. 'text[]') and
'tsvector'. For these we set new column profiles which set default
TableSpec properties to disable search/editing. This is just temporary
until support is added (but, in the meantime, we avoid db exceptions and
the columns are still viewable/readable)

Also note that this does not stop the user from manually setting different
TableSpec column properties...
