Title: Horizontal align right

I had a need to align background image to the right rather than left or centre.

The horizontal_center para only lets you choose to align centrally or not (left).

You could either allow this to accept a value of 'right' but I have introduced a new param horizontal_align as I think the name is more descriptive, and allowed this to accept values of 'left', 'right' and 'center'.

I have made it backward compatible with horizontal_center.
