Vadim Zeitlin ac02ae877f Add simple wxBitmapBundle::FromSVG() implementation using NanoSVG
Add nanosvg submodule and use it in the generic implementation of this
function.

This is incomplete yet and, notably, doesn't cache the rasterized
images, but already shows that using SVG images works (at least in the
toolbar sample).
