V1.1.0 - Some nice quality of life fixes

• Added some actual documentation!
• The app should now stay awake enough overnight to keep the clock synced so it wakes up again at the right time
• Some images weren't getting properly aligned, resulting in a white line at the top or side of the images. That shouldn't happen any more.
• Added a pause icon to more clearly show when the slideshow is paused
• forceClockSync false will make it so that NTP requests don't happen at all
• The app will now prompt you to disable battery optimizations when you open it (It may not matter any more with the first point, but better safe than sorry)
• Added images for when there are no pictures loaded and when an image fails to load
