Finished QueryDialog
Edit Entry Dialog - work in progress

Finally I managed to get the EditEntryDetailsDialog and the additional QueryDialog working.
Now when the user changes some detail of one Password entry and cancels the operation by left swiping he will be notified by another QueryDialog that there are unsaved changes. He can then afterwards save his changes if he whish. This should be more user friendly because the arbitrary user might miss the fact that left swiping cancels the edit operation.
