Fixed an issue with the transitions of the carousel, which failed to apply the next, prev, left and right classes when more than one CSS transition was set. This was due to multiple durations being returned as a comma-separated list (e.g. ".6s, 2s") which slice(0, 1) * 1000 would turn into a NaN.
The fix adds another function, findDuration, to the emulateTransitionEnd flow, which returns the highest duration in the comma-separated list as milliseconds. The function won't interfere with existing uses, as integers are ignored.
