Add hashes plugin (#1315)
* add plugin Hashes, containing hash and encryption related commands
* Hashes: make the default plugin Hashes when the commands are used by themselves
* Hashes: add supybot.conf because of registerDefaultPlugin
* Hashes: import registry to help with registerDefaultPlugin
* Hashes: add in nicks for test
* actually use hashlib instead of crypt, also s/'String'/'Hashes'
* Hashes/test: add group in for testing
* Hashes: add in changes per @GLolol
* Hashes: remove xor
* Hashes: make plugins = ('Hashes',) instead of ('Hashes') because python is weird
* Hashes: fix sha512 calling sha256, use utils.str.format on 'algorithms'
* Hashes: just use the variable instead of substitution per @GLolol
* Hashes: follow through with not using substitution
* Hashes: disable the 'algorithms' and 'mkhash' commands if the underlying 'hashlib.algorithms_available' isn't available
* Hashes: don't use registerDefaultPlugin its for core plugins
* Hashes: also somehow I didn't change the copyright
* Hashes/test: fix copyright in file
