New Chedot version/pattern

[jaydiablo]

Fixes #1569.

Added a new pattern for Chedot 8.0 which varies slightly from the existing patterns.

Added a 3.4 file as well, to catch some UAs we’ve seen. I didn’t think it was good to add 3.4 to the file that has version 43 in it, as we’ve never seen the Chrome/3.4 style pattern for this version of Chedot.

Also renamed the 28-on file since it only contains one version (43.0), which is also the only version in that style of UA that we’ve seen.

Added tests from UAs in our logs to cover any uncovered patterns.

Ah, and I did add Win Vista and XP to these patterns because their site mentions that the browser is available for these platforms: http://landing.chedot.com
