Version 2.8.1 - Bug fix release

This version contains several bug fixes, the most important are:

- Corrected issues with image rotation and trim on preview screen and in resulting documents discovered after v.2.8 was released (e.g. when the images were rotated in Picasa)

- Corrected hanging issue that occurred during image color quantization to grayscale on higher-end machines.

Please note that from this version two Fopydo icons are showing on the Dock by default: one for the GUI and one for the 'worker'. You can close the GUI on larger scanning jobs and the worker will continue processing images. You can recognize that the worker is still processing images if the Fopydo icon is still present in the dock.
