Subject: [PATCH] Don't manually set Content-Length in StaticFileHandler.

Content-Length will be set automatically in RequestHandler.finish.  This
change fixes a bug in which RequestHandler.finish's Etag support strips
the response body without changing any headers.  Transfer headers
(including Content-Length and Transfer-Encoding) are the responsibility
of the framework, not the "application-level" handlers (which includes
StaticFileHandler).

Closes #160.
