Add support for setting the width of the overlay crosshair and rectangle...

.... The default is 1, and can be increased in steps of 2 up until the size of the overlay. Add the Width records to the autosave req files. Make the Position and Size link fields optional.

More detail:

This only affects the cross-hair and rectangle, and has no change in behavior if the WidthX and WidthY are left at 1. In the template file I added the supporting records, and also changed the existing Position and Size DOL fields to be optional. I also fixed a couple of typos in the comments in the overlay header file.
