Accept user images

It'd be cool if the user could specify their own images via the front end. It'd be too expensive (and insecure) for my server to have them uploaded there. Instead it'd be good if the user could:

• Specify a list of URLs pointing to images in a textbox when making the game.
• Specify a remote directory full of images that it can use.
• Or something of the like.

I've taken a crack at this and it's proving difficult. Passing the link in via the URL is not working well, I would have to do some escaping and unescaping. The ideal flow is:

• When the user presses GO from the front page, if the field for the user supplied images is populated, it should be included in the POST request (not the URL).
• The server looks at the link and depending on characteristics of the link, one of two things happens:
  • If the link is a link to a text file, it should read the text file (which is a list of URLs, one on each line) and use the contents of it as the words (use these URLs as the value for s.imagePaths).
  • If the link is a link to a directory, it looks at the files in the directory and produces the URLs for s.imagePaths using that.

With s.imagePaths changed. the game should use the user's images.

The problem with using s.imagePaths is that this is global to the server, so this would fuck things up if multiple games are being played at once. You could maybe change it back to what it was before when you hit handleRetrieveGame if the user-supplied image link is empty. There could be races here. Ideally the images used would map to a single game, not the server, but that would be a painful refactor.

Maybe you could put the escaped link in the URL and leave it there. That'd make the images local to the game. I'm not sure if that works though to maintain state properly between players, though it should since everyone is using a link with the image source baked into it. You'd still have to attach it to the game object and not s.imagePaths though.

As of #15 this is done!
