**Allow field customisation when importing db tables **

PR Description:

This expands the database table import dialog to add a new field mapping section, which gives users control over the
fields in the created table. Users can rename, set the exact destination field types, and tweak the source expression
for each output field. Fields can also be excluded from the import, or new fields created which don't exist in the source table.
