Description

It would be nice to support the use of data urls on components like ImageView and WebView.

Ti.UI.createImageView({image: "data:image/gif;base64,R0lGOD

//or even on a webview
Ti.UI.createWebView({url: "data:image/gif;base64,R0lGOD

I know that Obj-C with NSURL should be able to do this.

NSURL *url = [NSURL URLWithString:base64String];    
NSData *imageData = [NSData dataWithContentsOfURL:url];
UIImage *ret = [UIImage imageWithData:imageData];

Also need this on Titanium.Media.VideoPlayer so we can upload the video to Facebook without re-downloading the video file to the devices filesystem. See [this thread](http://stackoverflow.com/questions/5355846/iphone-facebook-video-upload) for more info on how it works.
