This change adds an image slideshow screensaver mode with optional
background audio. The existing menu and video screensaver have been
refactored to include this new mode.
By default, the slideshow screensaver will show images from the
game list, but it can be configured in the menu to use a custom
directory instead.
- Final changes for VLC screensaver support as well
- ALSA de-init/re-init only when needed
- Adding screensaver options menu inside UI settings
- Slightly moved options (Show Frameskip to "Other Settings", sorting within same menu)
- Adding info popups on random video screensaver and OMX + Game Info setting
