Add FANUC TP language support

Hi there,

I have added support for FANUC's TP programming language. This is used for programming industrial robots.

Please let me know if there are any issues.

Best,
Jay
In languages that have units after numbers we traditionally either highlight them as part of a number ([like in CSS][1]) or don't highlight at all.
