HTTP / HTTPS support #55
Description
In the interest of time, we removed HTTP / HTTPS support from the initial duktape integration. We need to add that support back in for the examples, preferably using libcurl, although I'm open to other suggestions. pxScene runs on many different devices, including some embedded devices, so libcurl is a standard choice as it is available just about everywhere.
In addition, examples should be loaded via the initial browser.js by entering a URL, similar to how the regular build of pxscene works.
