Revision: 1921

Log Message:
-----------
move FileHelper over to tests plugin. Use core.util.Util to grab a file's content - that way we avoid the off by one per line offset issues in refactoring stuff we do. (on some systems they use more than \n as end of line delimeter, so many offsets that rely on that will be off by one character per line that precedes it)

Added Paths:
