Michael Kessler 5f0c815256 Cleaning up all specs.
I basically went through all specs and applied the following rules:

* Use `describe` for methods and `context` for contexts.
* All class methods starts with `.` and instance methods with `#`.
* Removed all `it should`, because the specs _have to_.
* Applied a consistant naming on all listener specs.
* Make fixture usage more fail save by giving generous sleep times.
* Make all behaviour description non-technical and easy to understand.

The goal of this excercise was to have a documentation that is easy
readable and describes the behaviour and not the implementation.

Try it out by using the RSpec documentation format!
