Add the ability to use "time" as "times" alias
Created by: benoittgt
resolves https://github.com/rspec/rspec-mocks/issues/1269
- I don't know if I did the right thing for the documentation
- Do we need that number of tests?
- Do we need to run https://github.com/rspec/rspec-mocks/blob/master/Rakefile#L42-L61 after merge?
Cheers
