Decouple parsing and formatting from OnGUI code for CI purposes

[bdominguez]

In our company we make builds using batch mode but it's really difficult that when a build fails, see a problem because you need to search in a +1000 lines of editor.log file.

Using "BuildReport" class we can at least log that information with "Debug.Log" API at the end of the log so we can have all this information in the same place at once.

I saw this package and I see that it parses and builds that information transversing the steps recursively and setting the appropiate depths.

My problem is that it's coupled in a unique class that also uses OnGUI API.

Can you refactor it so I can use your parsing logic but not the OnGUI logic?

Thanks.
