Added features:
	* 'mmgen-tool': file encryption utility with strong encryption
	* 'mmgen-tool': find hidden incognito data in file using the Incog ID
	* User may now supply additional entropy in all cases where random data is
	  needed.  This user entropy (typed symbols + keystroke intervals) is hashed
	  into a key with Scrypt and used to encrypt all random data produced during
	  the session by the OS.
