RFC: Pygments formatting enhancements


I just found out that pygments[1], a source code highlighter, also understands Igor Pro procedure files.
As I had some problems with it, I made some changes [2].

In case someone else wants to change something more, it might be a good idea to get one version for all our needs.

My pull request for pygments-main has been merged. Additional to some lexer enhancements it now also supports the "official" igor colors.
