Cesu8 (#44)

* cesu8 handler

* resume file cesu8 handle

* utf8 emoji filepaths

* cesu8 emoji filepaths and torrent names

* cesu8 emoji filepaths and torrent names handling
improve tests

* add fastresume Name field

* update golang ver

* handle torrent files with cesu8 encoded file paths and handle them as NoSubfolder torrents for better compatibility

* fix cesu8 named single file torrents
