New Features

• creates PDF from local images
• spec file for creating stand alone binaries
• Image name is cleared when stopped a scan session
• Image name has now auto complete, to avoid overwrite existing files

Issues

• The script is tested only with a HP CM1312 device
• Only one (the first) scanner is usable
• If the LED does not become green after the device is switched on, may be your device is not supported
• If the LED becomes green and the button keeps yellow, the scanner is locked by another device/thread
