Switch stickers to Vectors

[bahorn]

Right now, we are just using 181x209 pngs for the grid, which do not look good on high DPI screens.

Considering most stickers are made as vectors, it'd be better to just use SVGs and only use hi-res pngs for ones we don't have vectors for.

How easy is it to force the size of a SVG? It might even be easier to use something completely different to the hexbin.

should be just setting the width + height, which we already do.

Can be done by just replacing 'src': val.raster with 'src: val.vector ? val.vector : val.raster'

Still need to convert a few to SVGs and fix borders on them though. The DurHack one is an illustrator file, so will need to convert that. Maybe an extra link should be added so we can also include the raw documents so patches can be made.
