- Rewrite field mapping table selection logic - simplified logic, no longer tied to table list selection. Much faster selection of table to import into if, eg, content view is selected. Fixes weird crashes.

 - No longer display views as import targets
 - When one import has been cancelled, still allow new imports
 - Improve error reporting
 - No longer re-sort table/view/etc names returned by TablesList as preferred order is being used for display and the default compare: reverts this
