Some simple test for file parsing

With no V2 question shown
- parsing fails when a V2 file is loaded
- parsing succeeds when a V3 file is loaded
- import of CSV file succeeds

With V2 question shown
- parsing succeeds when a V2 file is loaded

Finally compare the output of reading in the various files with reference
output included in the sources.

My guess is that this test might be a bit fragile, but hey, it's a start.

(reminder: the tests only get built when using cmake)
