Can we add the exp extension to the to the tcl icon set? This is to account for expect, an extension to the tcl language. This would require changing the supportedExtensions.js file's line as follows:

{ icon: 'tcl', extensions: ['tcl'] },

becomes

{ icon: 'tcl', extensions: ['tcl','exp'] },

And this would probably better suited to me just issuing a pull request, but I don't have any experiencing with building via npm, so I'm pretty sure I'd get it wrong.
