Introduce toggle buttons which mean "filter all dives except those fulfilling the selected criteria". The old code used to check for rowCount() == 0. This should never happen, because there is always a row "empty field". This check was moved into the preamble of the functions to seperate it from the actual logic. Fixes #435 Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
