Remove duplicate of wi-owm-803.

Icon 803 for OpenWeatherMap is duplicated, I double checked, it should correspond cloudy-gusts.
Not sure if I made changes into the right place -- is api-list.html is autogenerated out of api-list.jade?

Yes. I have a project problem where I made the gh-pages for weathericons.io in the main repo, but the gh-pages is a different branch, so I have to copy the actual good files from the real repo to that branch, and I don't have a better way to do it that I've thought of.

The actual weather icons set had this fixed, it was just the display page and the api-list.html documentation that had it. So thanks for finding this. I need to find a better way to do this.
