Number button: Bugfix for strike representation
Bee: Graphics update and animations
Bee: Bug fix for add/subt methods

The bee went way too far on the forced attempt after a round was
finished.
Number button: positioning tweaks
NPSubgames: Bugfix for button updates

The buttons updated before fading out when in "agent try"-mode. This
solves the problem.
Birdhero: Slight zoom adjustement

The lowest branch was obscured by buttons.
Skipper: Check if current skipper is parent

In case a nested timeline wants to skip and the parent already does, use
parent instead.
