Bug#339966: webalizer crashes on (compatible; Googlebo t-Mobile/2.1; +http://www.google.com/bot.html) agent

[Jose Carlos Medeiros]

The problem occurs only if using a MangleAgent level of 1, and only on
some of the newer browsers that have multiple parens ('(' and ')') in
their name.  Workaround is to use anything other than 1 for the
MangleAgent level.
