clogger 1.1.0 - more escaping!

This release fixes potential vulnerabilities when escape
sequences are viewed in certain terminals.

The 0x7F-0xFF byte range is escaped to match behavior of nginx
1.0.9+, as some character sets may have escape characters in
that range.

$cookie_* values are now escaped to be consistent with the
behavior of the $http_cookie value.  All users of $cookie_* in
their log format must upgrade (of course there may be no
Clogger users other than myself, and I don't use $cookie_*)
