ve.dm.MWImageNode:
* Define sensible scalable properties for audio files. They are now
scalable to any width but have a fixed height. (Ideally they would
have no concept of height, but that would require many more changes.)
This prevents them from resetting to 0x0 when resized.
ve.ce.MWBlockImageNode:
* Remove override for #isResizable, audio files can be resized now.
* Move #updateMediaType to MWImageNode mixin so it applies to
MWInlineImageNode as well.
ve.ce.MWImageNode:
* Add #updateMediaType from MWBlockImageNode.
* Hide the real image 'src' using CSS rather than changing the
attribute. It seems the previous solution depended on the order in
which methods are called, because it stopped working when I moved
the code here. (This depends on VE/VE change If5b1b5b5d.)
audioPlayer.svg:
* Make the file nicely resizeable. The dimensions of the "play" icon
and time are fixed, the bar adjusts to the width of the container.
