SVG Style parsing

[wolfv]

Hi cjlano,

I wanted to send you a private email, but didn't find your contact details on gh.

First of all, thanks for the great svg parser. Works good so far and has some improvements over the one I made for my project.

I needed CSS style parsing so I implemented a rough version of it here: https://github.com/asl-beachbot/pathmaker/tree/master/python/svg

You may or may not be interested in the changes I introduced, but I thought I'd let you know (also in the spirit of the GPL :+1: . Maybe it's a welcomed addition for other users as well.

Cheers,

Wolf
