Bug 1855771: Allow generic system errors to give more detail

So that we can debug things easier

The Exception class has two useful methods, getFile() and getLine()
so we can use these to dispaly where the problem is rather than just
a generic: exception(object(ParseError)) at Unknown:0

To test:
- a syntax mistake - add a log_debug() line before the first function in a class
and see if the error shows the correct file/line
- MaharaException - add the following line somewher ein the code
throw new MaharaException("Missing bananas");
and see if the error shows the correct file/line
