Use SVGs that render even if the user doesn't have the font installed

I added new SVG logos in 693e367 and cb56e70.

These were copied from the brand repo. What I didn't think about then is that the SVGs use <text font-family="Insignia LT Std"> which will only render correctly on machines with that font installed.

Using web fonts is not a good solution since these SVGs aren't only going to be used on the web - they'll be used to create swag, printed material etc.

So I modified the logos in the brand repo to convert those <text> elements to <path> instead. That means they can be rendered correctly without the font installed.

The SVGs in the commits above must be re-updated to use the new SVGs
