Add an option that allows to export a minimal HTML version of the Fittings

[Timmeey]

I ran into the problem, where i could not add the HTML generated by the Export option, to a website, because the Editor is stripping almost all tags (<style><script>....) and to get the generated html code to work, was a LOT of effort, because i had to manually remove this/that add this/that.

It would be nice if there was an option, that tells pyfa to export a minimal version, without any styling/lists/javascript etc.

So i went ahead and added this option to pyfa. it works great and produces really simple html output that works in game and oog. #611
