Convert Images to Combined PDF 1.0

**Function:** Converts the selected images to a single PDF file.

**Notes**: Files are ordered based on ascending name (since the Finder doesn't pass selected items in the order they appear in the Finder window) but this can be changed by editing the workflow. The resultant PDF is opened in Preview and will need to be saved manually (the file is created in /private/tmp).
