Cache Token objects to improve performance.
The Token class now contains a cache of tokens, and each token stores its encoded value. In Python 3 this prevents encoding the Token commands (get, set, incr, etc...) repeatly. There is also a smaller performance improvement by creating fewer objects. A very basic benchmark script was also added.
