Remove preg_quote() call from CI_User_agent::_set_browser() and add another pattern for Opera
Input comes from a configuration file that is barely touched by anyone
and the default values only contain letters, so it is safe to not
quote them.
This enables us to add a more advanced pattern in config/user_agents.php
for Opera 10+, which ... quote:
Opera/9.80 is hard coded at the beginning of the user agent string because of broken browser sniffing scripts which detect 'Opera/10' and above as Opera 1.
(reference: http://my.opera.com/community/openweb/idopera/)
Instead, latests versions of Opera append ' Version/<version number>'
to the end of the user agent string.
Fixes issue #555 (incorrect browser detection for Opera)
