Several Minor Fixes and Tweaks

Proof:
* Changed conflicting variable names with Output script.
* Fixed Illustrator recognizing valid paths with only two points.
* Fixed recognizing multi-color napkins so they only print duplex when
they are two-sided.
* Fixed setting the art frames on multi-color items to multiply if the
art has a multiply'd item in it.
* Added a catch in case the Proof PDF file could not be saved (due to
being open on another computer on the network).
* Bumped version number up to v2.62.
