Add mass test data testing. Currently the test fails completely.

All files in the data directory (relative to the working directory of the application) are read, and each line
will be split at the colon. The left part will be used as the SI number and the right part as the frame.
Change the way SI numbers are choosen for dumps in the punchVisualiser

Instead of a text edit there will now popup a list will all known SI numbers. Just double click the right one.
