Eirik Aavitsland c23e3f4822 Add commandline option to lancelot tests for forcing baseline update
Normally done through the webform, but this option is useful for
scripted running of such tests.
Also option to disable such updating alltogether, to allow runs
that will never modify the baseline suite.
