browser:resourceDirectory files ending with .htm should be handled as .html files

[toelooper]

In a project I import javascript/html files from an external project via <browser:resourceDirectory...> directive without modifying the orginial files. The javascript library includes some .htm files and while published by zope a wrong base tag is included.
