Subject: Followup to PR #1142 Fixes a threading bug in where lazy reading of
 file caused a problem for multithreaded access to the that was read.

Changes all uses of io.Source to use new API
getText
getLines
getTextResource
getLinesResouce

Make style to only import FileUtils and not its methods
So code is more explicit as e.g. FileUtils.getText()
