Moved auth tokens to separated (uncommitted) file.
Moved AuthTokens.java to its own folder 'auth'.
Random changes.
Merged TopicFileReader.java and CacheFileHandler.java into DataReader.java.
Added (untested) functions to save and load dev keys.
Removed unnecessary methods.
Implemented dev key saving and loading; not functional at present, may have to drop encryption (eew.)
Set to store dev key in plaintext; will be undone once ciphers are working.
