Changed the OSU library "rename" to include the (nonstandard) ".tlef"
extension. Also, noting that the check for names after "rename=" that
do not have file extensions is incomplete, added a case for "techlef"
and a catch-all case at the end. This commit effectively implements
Amr's pull request #46, but in a slightly different way.
