Catch out of memory exception when forced to rotate the bitmap, if out of memory, try to load a smaller subsample
If the smallest sample we want to use still can't be loaded, throw an IOException for now to avoid crashing
set HARD_CACHE_CAPACITY to 0
added try catch for OOM in ImageFetcher
automatic clear the cache on OutOfMemoryError
Added the ability to return errors in resizeImagesTask, so that failed attempts to import will call return as errors, differently than cancelling. Also some whitespace fixing.
Pass back the actual error string when an error occurs picking images
