Implement dynamic loading of slide resources

Implements loading of textures and images during runtime instead of load
time.
- Images which are not part of any slide are loaded at load time
- Master slide images are always loaded at load time
- Images used in a slide are loaded when the slide is entered
- Images are unloaded when slide is exited and any other slide does not
  use them
