Updated importing to use a wizard, instead of direct-dialog
Preparatory for adding field-association to importing. Current functionality should be essentially identical to previous, except in a wizard.
Super basic import field associating
Still plenty to do, but you can now tell it which source columns to import as what csibox fields on import, with some unit information.
updated importer to show errors as-imported on confirmation
Finish up importing functionality (for now)
Added labels to fields, functionality on final wizard import page. Still to do (later) is making error selectable via field, rather than name, and making source unit a drop-down and doing conversions (oh boy!)
