Fix preferences cache 

* Fix the problem that preference cache was not reset when `setPreferredSomething` was called, only when `edit(preferred_something=)`
* Implement something more advanced than just `portal_cache.clearCache()` so that when a user change their preference, only preference of this user are affected.
* Increase default cache duration, now that we invalidate caches properly.

      I'm getting an AttributeError: clearCache in this line on 2 instances I updated. I checked carefully to have the instances and bts properly updated to discard a problem on my side.

      I get the error when changing or editing a preference, so it blocks these instances to set the VCS properties.

      Before I start to investigate in detail, I want to check if may be this is a known issue or I'm missing something to get this working.

      Please make sure that you have updated the products and restarted zopes before updating business templates. This clearCache method is defined here

      True, I was missing to restart the zopes. It works fine. Thank you !
