Ask what do to in case of inaccessible app / fav dir


when storing the SmartFTP app data and / or favorites on a network drive, DropBox, or similar, that drive might not be available when starting SmartFTP (e.g. if the user forgot to mount it). In that case, SmartFTP silently resets the app data / fav directories to the defaults when starting.

IMHO, it would be much nicer to have a simple dialog popping up that asks the user whether to simply exit / do not run SmartFTP (in order to give the user the chance to mount the drive and restart SmarFTP) or to continue starting and reset to defaults.
