Suggested changes to support the history=1 parameter

[Nathan Wallace]

The bit.ly API allows for history=1 to be passed so that links are
added to the users bit.ly history. Unfortunately this is not supported
by python-bitly at this stage. The patches to two methods below will
enable a parameters option to be passed to shorten() supporting extra
fields like history.

Couldn't work out how else to best submit this change. Thanks for a
great tool!
