Add RSpec 3 support
Revert "Depend on RSpec-expectations, not RSpec"

This reverts commit 8fdd8d2b3c725a2156690458ac7dbc36d5cdd94a.

Cucumber integration relies on RSpec-core.  Possibly it could be
reworked but until then RSpec dependency is back.

Update matcher protocol for RSpec 3

"Update matcher protocol and custom matcher DSL to better align with the
newer expect syntax. If you want your matchers to maintain compatibility
with multiple versions of RSpec, you can alias the new names to the old.
(Myron Marston)
* failure_message_for_should => failure_message
* failure_message_for_should_not => failure_message_when_negated
* match_for_should => match
