addCompletionListener callback parameter

[Chris Percival]

The documentation shows callbacks supplied to addCompletionListener get called with an event parameter, but it appears they don't. It would actually be useful if they did.

[Felix Dürrwald]

I fixed this by adding e as a parameter to callback in PxLoader.js on line 85.

Lines 84 to 86 should be:
if (e.completedCount === e.totalCount) {
callback(e);
}

Sorry about the delay. Thanks @mplabs for the fix!
