Modified the command-line support to accept wildcard character asterisk in input specification.
Example: JPEGtoPDF.exe "C:Output.PDF" "C:Images*.*"

10-09-2011:
Fixed an issue with conversion to a single PDF, which would limit the PDF page size to a max of 17"x17".

09-02-2011:
Fixed a setting not saving correctly (saving opposite) for page size (image size versus specific size).
Minor fixes. Conversion might be a little faster now.
The file list does not allow duplicate entries. Perhaps this should be changed..

08-22-2011:
Fixed the "Browse for Images" dialog not matching image types with their extensions correctly.

07-28-2011:
When determining the number of pages in an image, .JPG files (and all variations) will be treated as single-page images.

07-19-2011:
If the program is saving a single PDF, and that filename does not end in .PDF, the program will now automatically add the file extension.

07-15-2011:
Added support for Windows 9x.
