Fair amount of new functionality at this point. Works as a reasonable replacement for other image viewers plus has better support for dds files and loads gifs faster than some. Can now flip and rotate images (does not auto save them). View dds mipmaps and all sides of dds cubemaps. Pixel colour may be inspected in fullscreen mode in the information overlay (press enter to toggle overlay). Skip to beginning/end buttons added. Directory changes are synched when window receives focus again by comparing 256 bit hashes. Various bug fixes.
