Title: Add support for lifting methods with no arguments.

Since lifting supports `void` return methods by sending `RACUnit.defaultUnit` I thought it would make sense to support methods with no arguments by having one signal that sends `RACUnit.defaultUnit` (although it actually ignores the values the signal sends completely).

Details aside, I think not being able to lift methods with no arguments is a pretty big feature hole.
