url.py: removed 'file' inheritance in the httpsendfile class
Since py3k doesn't have a "file" builtin and, consequently, doesn't support
inheriting from it, this patch refactors the httpsendfile class to wrap the
objects returned by the builtin "open" function while adding the necessary
methods (__len__ for constructing the Content-Length header and read, write,
close and seek for the file-like interface).
