Title: Updated class to cater for foreground (transparent shadow overlay) on bu...

Hi, I have edited my copy of the class to allow for a foreground image as well.

My button images actually comprise of 3 layers - the background, the button itself and an overlay over the top to provide a 'shadow' effect.

The changes here work fine when I tested. They may be useful in the main branch for future users...?

Thanks,
Devan
