SVG support

With the web being responsive nowadays and people working on a myriad of different resolutions and screen sizes, it would be nice if SC allowed for .svg files to be uploaded into the images library. Browsers handle them like any other picture anyway, as long as a width is provided. This wouldn’t be a lot of work to implement, would lower bandwith / page load speed and would mean icons can just be uploaded in ?ne format instead of an plethora of different sizes.

Since they’ve got transparency, it might be handy to include a checkerboard / dark background in the image selection modals. Currently, it’s quite a pain in the behind to choose a transparent PNG that’s got a white icon; since it shows them on a white background.
