bugfix rest-client 1.7.1 and 1.7.2 released

Andy Brody <andy@...>

Hi folks,

We've shaken a few bugs out of the 1.7.x branch. Errors on duplicate
CA certificates on Windows are now gracefully handled. Rest-client
will now allow but not depend on mime-types 2.0. A large number of
gems had dependencies on mime-types ~> 1.x, which meant that they were
incompatible with the pin on ~> 2.0 that was temporarily introduced by
rest-client 1.7.0.
