Title: Add flush method to throttled observables

In a current project I use a throttled observable for submitting a form 500ms after the user has stopped changing the value. I also wanted to provide instant feedback when the user presses the enter key. With the current implementation of the throttled extender this was not possible in a straightforward way so I added a `flush` method.
