Cannot load URLs with special characters

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use a SceneUrl URL like "http://example.com/foo%20bar.stl"

What is the expected output? What do you see instead?
- Even though the URL is properly-encoded, it fails to load the file.
- On the network, it shows that it actually tried to open 
"http://example.com/foo%2520bar.stl"

What version of the product are you using? On what operating system?
- Latest SVN Checkout
- Google Chrome Canary 40

Please provide any additional information below.

This happens because it calls `encodeURI` on the URL even though it is already 
properly encoded. To prevent double-encodings, `encodeURI` should not be called 
here but by the implementor that uses the links if he thinks his URLs are not 
properly encoded already.

The attached patch removes calls to `encodeURI` and fixes the problem.

I just found a discussion on a similar issue on stackoverflow: 
http://stackoverflow.com/questions/2295223/how-to-find-out-if-string-has-already
-been-url-encoded?lq=1. It enlightens me that since decodeURI() is harmless, 
maybe we can decode an URL and then encode it again like this:

  encodeURI( decodeURI(url) );

I think it should produce the expected result whether the given URL has been 
encoded or not. Not sure. Still needs more tests.

It seems to work as intended. If you think people might enter unencoded URLs, 
this would do the trick!
