Changes with nginx 0.7.11 18 Aug

*) Change: now ngx_http_charset_module does not work by default with
   text/css MIME type.

*) Feature: now nginx returns the 405 status code for POST method
   requesting a static file only if the file exists.

*) Feature: the "proxy_ssl_session_reuse" directive.

*) Bugfix: a "proxy_pass" directive without URI part might use 

request after the “X-Accel-Redirect” redirection was used;

*) Bugfix: if a directory has search only rights and the first index
   file was absent, then nginx returned the 500 status code.

*) Bugfix: in inclusive locations; the bugs had appeared in 0.7.1.
