- added file chooser
- changed file/dir entry box for a button that opens the file chooser
- added dialog to ask if you want to select a dir to scan or a file
- fixed bug where you could abort as dialog opened and the dialog wasn't cancelled
- fixed crash where you could abort as the merge prompt opened and it would try to use the just-destroyed importer
- fixed bug where closing the application at the end would show "aborted!" erroniously
