Implement a nice viewer for result and log files

[Nicklas Nordborg]

Log files and other result files from the secondary analysis often have mixed output with text information and some data tables (eg. Picard). It would be nice to have a viewer that can re-format the files so that tabular data is viewed as a table. This would make it a lot easier to align headers with data (again, mostly needed in Picard output files, but may be nice also for other types of files).
