BUG Check for existence of HTTP_USER_AGENT to avoid E_NOTICE error.

Browse Source 
In some cases, a request may not have an HTTP_USER_AGENT. This should
check the variable exists before attempting to check it. The specific
case where it failed for me was Active Directory Federation Services
sending a web request to a SilverStripe site, but failing because it
doesn't have an agent string.
