This PR aims to improve highlighting of the message log. When you start a LaTeX compile the log shows a green line with the build command. This is because the line contains .tex from the file name given (including extension):

But not in all cases a command uses the file name including extension. For example, when you run Biber all log lines are black:

So this PR will change the color to green for all lines, which would be black under the same conditions, but contain Process started::

This helps finding quickly the start of the next process.
