support .wav and .m4a for embedded media

[Kristina Hoeppner]

.wav and .m4a, 2 formats that are produced natively by iOS devices should be supported in the "Embedded media" block. That means they'll also need to be able to be turned on or off at /admin/extensions/pluginconfig.php?plugintype=blocktype&pluginname=file/internalmedia (Admin menu -> Extensions -> Plugin administration -> Plugins blocktype internalmedia

It will need to be checked if both formats can be served by our internal HTML5 player video.js or if it's only m4a.
