Launch profile for Opera should set collections of stats settings

[IgorMinar]

When started Opera occasionally prompts the user to opt into collection of usage statistics. This prompt window currently causes Testacular to stall and wait indefinitely. If the prompt dialog is not manually closed, test run will never make a progress.

There doesn't seem to be a command line switch to suppress this behavior, but I'm guessing that if the setting is explicitly set to either yes or no (likely no is a better option since we don't really use the browser in a normal way), the dialog will not show up. To set this option, we'll have to generate or edit the opera profile ini file when creating a profile for the run.

Check out http://www.opera.com/support/usingopera/operaini/, specifically section "Enable Usage Statistics".

It should be easy to just create a new profile, then set this setting and see what changed in the ini file.
