Commit May 31 2014 Python file encryption and decryption

The python version now supports encrypting and decrypting entire files.

Modified Files:
	.gitignore:
		Ignores the vim lock .swp format.
	readme:
		Has been updated to reflect the additional arguments
		and better description of the program.
	rsa:
		Has been modified to handle entire files.
		The structure of argument checking has also been changed.
		It checks the length of the argument, then all of the arguments
		of that length, instead of checking both each time.
		i.e nested if/elif/else blocks instead of single-level blocks

	rsa.c:
		Still working on getting something that works. It is evident
		that using power will not work, so I'm trying something different
		using multiplication and modulus.
