Optimise SVGs

Removes all meta data, especially this massive inkscape block, which only affects how the SVG is shown in this software, the default window size position, and all this crap, which has abolutely no space in SVGs used for websites.

Furthermore syntax paths were optimised for minimal code size.

All lossless, i.e. the image looks exactly the same.
