Process now checks if a film's specific resolution is already uploaded to ANT as well. If the resolution is missing then it can likely be uploaded even if the film exists on ANT. If the resolution can't be extracted from the file name, then it will just check if it exists on ANT.
If a film_list.csv is found from previous versions, this won't be compatible with this new update, so if a file is found, this is backed up in case users want this to be kept.
Fixed error handling logging messages and added messages for specific status codes user might encounter.
Closes #16
