Workaround iTunes' incorrect registry entry for .m4a extensions.

[Jer Noble]

When iTunes is installed, it adds a registry key: "HKCR\.m4a\Content Type" = "audio/m4a".  QuickTime (without iTunes) installs the same registry key as "Content Type" = "audio/x-m4a".  QuickTime explicitly does not support "audio/m4a" codecs MIME types on either Mac or Windows, so .m4a files fail to load in WebKit when iTunes is installed.

[Jer Noble]

Work around this by adding a hard coded entry to the MIME type map of ".m4a"->"audio/x-m4a".

I think the existing list is sorted in alphabetical order by extension.

It looks like it's sorted in willy-nilly order.  Would you like it to be sorted in alphabetical order?
