Displays description of images/videos, Bug fixes

This version presents the description of photos/videos in preview mode. The app now also better manages the situation where an album has been deleted from a browser. The album/image data cache is better exploited and the search tool is slightly improved (avoids a situation where a placeholder is displayed instead of the image).

This version also fixes:

• two different crashes which can occur at start-up,
• the inability to download thumbnail images whose filename contains a space,
• the position of favorite icons on iPads,
• the laggy scrolling of thumbnails in albums,
• a crash occurring when trying to copy/move a selection of photos on iPad,
• a crash occurring after having deleted an album with a browser.
