Test case with non zero start time

[sebapersson]

Adding test-case with non-zero start-time. Unlike test-case 0018 this does not have pre-equilibration.

Arguably this test-case should come before 0018 as it should be easier for importers to pass, but I believe sorting the test-cases in terms of difficulty should be a later PR.

Added as 0029, so it can be merged after #105.

That was also my plan at some point, but I think it's hard to maintain. Also, the difficulty might be somewhat simulator-dependent.
I am happy to see them sorted, but I think just adding a comment like "this is a more tricky version of XYZ" might also do the job.

I think this is a good suggestion, as indeed how hard a test-case is depends very much on the importer. I have added a short text in 0018 referring to 0029.
