Changes since 0.9.5.1:
* Images can be now auto-rotated by images dimensions (not by EXIF data).
In other words, image is rotated if image's orientation is landscape.
A new command line option (-r, --auto-rotate) has been added to enable/disable this new feature.
* Added timers to auto-hide image viewer navbar and toolbar.
A new command line option -d (--bars-disappear-delay) has been added to adjust auto-hide delay of this new feature (disabled by default).
This feature is disabled if delay is 0.
* Added the index of the image, the total number of images and the image's size in addition of the image's name in the image viewer.
* Added a slideshow functionnality.
A new command line option -s (--slideshow-delay) has been added to adjust the interval (default 4 sec.).
