New photo frame version 5.6.1

Highlights of this version are:

• Transitions : Next to fade-in/fade-out, there is also a dissolve transition which shows the two photos blended together. More transitions to come ..., I'm open to suggestions.
• Completely redone recent slideshows. There is now the possibility to
• Rename the slideshow to whatever you want
• Delete the slideshow from the list
• Start the slideshow using the button next to the slideshow
• Go to the folder represented by this slideshow. This is a very useful feature if you often show photos from a subfolder of a certain location.
• The recent now has a (R) at the end to indicate it is a recursive slideshow.
• UPnP should now retrieve the photo with the best resolution instead of just the first one (depending on the server this would be an ok one or just a thumbnail)
• Unreadable photos crashed the app, this will now show nothing instead.
• Fixes the bugs introduced in 5.6 impacting a lot of users, sorry for this.
