F-Modifiers now work on 'all' types of NLA Strip. To get them working on Meta-strips, F-Modifiers on the Meta strip must be applied on top of those for child strips. For now, this is done by joining the lists of modifiers, and evaluating the joined list. Currently, Transitions don't work that great with F-Modifiers yet (only the endpoints get evaluated with the F-Modifiers). Solving this is for another time...
