m4a audio files not allowed from android audio recorder

[pontifier]

Android audio recorder is a default option when adding an audio file to a post from chrome on android. m4a files created by recorder are rejected with the message: "Sorry, you are not allowed to upload this file type."

It appears that an incorrect mime type is responsible. The mime type generated by the android recorder is 'video/mp4' while functions.php expects an 'audio/mpeg' and moxie.js expects 'audio/x-m4a'
