Tons of changes. Moved a lot of the book list logic into ApiAccess (in SearchResultsActivity), implemented basic API to list view functionality so that clicking search brings up books/authors/images from the API, and created DownloadImageTask which is currently and potentially indefinitely unused. If there's anything on here that makes absolutely no sense to y'all, let me know, there was a lot of slicing of code and whatnot going on!
