Title: Add convenience method for delayed schedule on RACScheduler

Method `-after:schedule:` takes `dispatch_time_t` argument that is in nanoseconds.
New method `-delay:schedule:` takes `NSTimeInterval` as argument (in seconds) and
calls `-after:schedule:` with calculated dispatch time. Method is implemented
in superclass and is not abstract.
