More identification work
- Add a finger selected signal, so that when an "automatic" finger is selected for verification, we know which one to scan - Fix the finger print numbers list to use GPOINTER_TO_INT / GINT_TO_POINTER - Make sure the gallery is NULL when there's no prints available - Don't use identification when a finger number is provided - Add support for selecting the finger number in verify - Add support for fatal warnings there as well
