NEW UPLOAD: sound, 10 levels and resolution bug fix

Hey all, I've now got a new version of the game built and uploaded for any and all to try out.  The new features are as follow:

1. Repulsors added (so now there are two types of pillar to interact with.
2. 5 new levels to use the repulsors in, alongside the attractors (new total of 10 levels.
3. Ball sound.
4. Attractor and repulsor sound (it's not great, just a placeholder until I get something better).

I have also fixed a bug where if you were loading the game in a full screen resolution that was lower than your desktop resolution you couldn't select the higher resolutions.  This is now sorted... hopefully.

As always, please download it, have a blast and give me any and all feedback.
