Detect CrMo

[eserte]

There seem to be a number of "Chrome Mobile" browsers which have a "CrMo" bit in their user agent strings. From my access.log files:

"Mozilla/5.0 (Linux; U; Android 4.0.1; de-de; Galaxy Nexus Build/ITL41F) AppleWebKit/535.7 (KHTML, like Gecko) CrMo/16.0.912.77 Mobile Safari/535.7"

Currently these are detected as safari 2.0, which is probably wrong.
