Local manga in zip/cbz/folder format (#648)
* add local source * small fixes * change Chapter to SChapter and and Manga to SManga in ChapterRecognition. Use ChapterRecognition.parseChapterNumber() to recognize chapter numbers. * use thread poll * update isImage() * add isImage() function to DiskUtil * improve cover handling * Support external SD cards * use R.string.app_name as root folder name
