AE: Pulse Audio fix resume between song change without crossfade
Merge pull request #2214 from fritsch/pa-fix

AE: Fix resume after song change with Pulseaudio
Corrected parameters order in Control.setAnimations

The documentation states that setAnimations receives a list of tuples,
every tuple being a pair (event, attr), for example:

self.button.setAnimations([('focus', 'effect=zoom end=90,247,220,56
time=0',)])

This patch corrects a bug by which the order of the tuple is reversed,
breaking Python scripts which send parameters in the order stated by
the documentation.
