* Config File Encryption: Configuration files are AES-256-GCM encrypted with a password and the scrypt KDF.
* Password Encryption: If the configuration file is not specified as command line parameter, it will be put into the base directory. The filesystem can be mounted with the password only, without specifying a config file on command line.
* Logfiles: Added a --logfile option to specify where logs should be written to. If the option is not specified, CryFs logs to syslog.
* Running in Background: Fixed daemonization. When CryFs is run without "-f" flag, it will run in background.
* Better error messages when base directory is not existing, not readable or not writeable.
* Allow --cipher=xxx to specify cipher on command line. If cryfs is creating a new filesystem, it will use this cipher. If it is opening an existing filesystem, it will check whether this is the cipher used by it.
* --show-ciphers shows a list of all supported ciphers
