- Works in IE9

Browse source 
- Fix issue with Quality Label not changing
- Immediately displays loading spinner on resolution change
- Listens to 'timeupdate', 'loadedmetadata', and 'loadeddata' events when resolution changes, because these events are fired inconsistently depending on device (iOS mostly), browser, and filetype.
- Auto-formatted file (spaces to tabs)
