Missing Magazine Article in tagged endnote publication type mapping

After multiple attempts I found that I couldn't successfully add and map to Biblio a new 'EndNote Tagged Publication Type' for 'Magazine Article' using admin/settings/biblio/fields/typemap/tagged so I edited biblio.type.mappper.inc and added the mapping there, which I think was meant to be there anyway as it is there for the other input formats. I then rolled back my database and reinstalled the module and the mapping is now there.

I have attached my first Drupal patch so I hope it's okay (it worked for me) and that I've submitted this issue correctly.
