This commit detects if the macos-only utility `iconutil` is available in
the PATH, if it is, then the icns is built as usual. However if it
isn't (such as on a linux system), then it checks for `png2icns` and
uses it if possible.

I'd like to think of this as temporary, until I get to rip apart riot-web
and riot-electron

Also add script for generating the PNGs and add pre-rendered PNGs
for the Linux electron build which means you don't need icns2png
to build it and the Linux icons are straight from the SVG rather
than resized bitmaps.
