Ability to upload SVG for app icon/bookmark icon

[grimvx]

Loving this so far. Not sure if it's possible, but the ability to upload custom SVGs along with the standard PNGs and JPEGs would be awesome considering MDI doesn't cover some of the app icons and bookmarks I use. Primarily I'd like this because it would mean I wouldn't have to shop each of the icons if I decide to change the theme or colors in css.

In an attempt to find a workaround, I tried to install Simple Icons with npm into "client/node_modules" but after looking at the JS in the static folder for Flame I learned it wasn't going to be as easy as drag and drop.

Thanks for the awesome app!
