* Add encryption
In order to avoid the server being able to read the content of the scene, this PR implements local encryption and decryption. This implements the algorithm described in #610.
Right now the server doesn't support uploading binary files. I mocked the server with comments. @lipis, could you add support on the server and update this PR? I added a bunch of TODO: that tell you where to comment/uncomment in order to get the server flow going.
To test locally right now:
- Import: Open http://localhost:3000/#json=1234,5oYVOnGpWYPPTz19-PMYYw and see a square
- Export: Click the export link and see the right url with the private key + the encrypted binary in the console
Fixes#610
