lang/qt/tests/run-verifyopaquejob.cpp (struct CommandLineOptions): Add
member processAllSignatures.
(parseCommandLine): Add command line option --process-all-signatures.
(main): Pass new option to the job.
--

The new option processAllSignatures is added to all jobs that verify
data signatures. By enabling this option, one can tell gpg not to stop
checking signatures after the first bad signature.
