#177 Add command line switch for generate batch reports

[Gadenz Alex]

The Batch report is a great feature as you could store defined report parameters in a file. It would ease the work if it would be possible to pass file names of batch report files on the command line and GenealogyJ would just generate these reports and exits afterwards.
I've tried it locally with a bad hack and noticed that there will be several issues to solve:
- starting without GUI
- passing file names as parameters to batch report
- passing e.g. names of output files to batched report
