    2.1 - bug fix with Livesplit 6.0 version, new split file format.
    2.2 - Add "Average Time Loss" and "Attempts" columns  
    2.3 - bugfix "Average Time Loss" was innacurate, it now ignores skipped splits.
        - Add "Inject Even PB to Splits", grav's idea to create a LiveSplit comparison with an normalized deviation from best splits. Explained here: https://twitter.com/graviton29/status/942946449528164352 This creates a new splits file with the injected comparison. Don't want to ruin someone's splits.
