Fix line end character stripping for Windows

LogQuery Spark example would produce unwanted result when run on Windows platform because of different, platform specific trailing line end characters (not only \n but \r too).

This fix makes use of Scala's standard library string functions to properly strip all trailing line end characters, letting Scala handle the platform specific stuff.
