Subject: Usage of the -d opion corrected Giving an error when a wrong -d
 option is given. Made some error mesages more consistent. Corrected usage of
 the exit call, in case of an error: exit(1) otherwise exit(0). A closer look
 should be made on exitDoxygen as it does not contain any exit statements and
 it is unclear (to me) when it is used.
