Patch for additional common mpeg 4 mime types

Tomcat correctly serves MPEG 4 files with a standardized file extension of .mp4, as video/mp4.

Common but non-standard mpeg4 files also use of the extensions .m4a and .m4v, which are unknown to Tomcat and are therefore served without any "Content-Type" header. This behaviour leads Internet Explorer to display garbage when following a link to such a file.

This patch adds the correct MIME type for MPEG 4 files with extensions m4a, m4b, m4r and m4v. (It omits the m4p extension, which is both not widely used, and of limited interest since the data is encrypted.)
