Replace the ai file with an svg vector file

Hi,
for the open source nature of the project it would be more convenient if the .ai file would be converted into an svg vector file. More (open source) tools can read that file format.

I made an SVG fork if anybody is interested. Since I made it for my own purposes, it includes some icons not included in this set and is missing some icons that are a part of this set, but I think people here will still generally find it useful.
