RSpec 3 Compatilbity

[coding-bunny]

Hello,

Running CanCanCan under RSpec 3 produces some deprecation warnings:

Deprecation Warnings:

`failure_message_for_should_not` is deprecated. Use `failure_message_when_negated` instead. Called from /var/lib/jenkins/.rvm/gems/ruby-2.2.2@riskmethods/gems/cancancan-1.7.1/lib/cancan/matchers.rb:19:in `block in <top (required)>'.

`failure_message_for_should` is deprecated. Use `failure_message` instead. Called from /var/lib/jenkins/.rvm/gems/ruby-2.2.2@riskmethods/gems/cancancan-1.7.1/lib/cancan/matchers.rb:15:in `block in <top (required)>'.

Would be cool to have these switched into the new methods.
was originally reported here as well : ryanb/cancan#997
