Add support for 2 new checkers and a few minor bug fixes.

I have added 2 checkers
cpplint and cppcheck

I have also make the tmp files have extensions so that the tools can detect if they can run on the file or not.
Finally I have stopped in publishing a review when nothing has changed. (otherwise I get lots of ship-its)

The 2 new files have BSD style licensing - which I hope is ok.
I have added my name but no email address (to avoid spam)

Any questions let me know.
Cheers
Dan
