Triggering pause doesn't change the "playing" status, which restores the correct pause behavior
Fixed and extended playback events annotations
In jQuery 1.9.x, binding of empty string (`""`) no longer results in no binding and an empty binding is created instead.  For non-wheelable setups this leads to stack overflow issues when unbinding such events at teardown. Using `null` avoids this and fixes issue #175
Merge branch 'gh-175-non-wheelable' into 1-2-1
