Rules should now contain all predicates necessary for matching the right
simulation movements. Which they now can do since they all have "Predicate"
tabs now.

The 'test' function seems to disappear in a few contexts. This should be fixed in Chameleon, but we work around it here for now

Commit 2f881b06 was a wrong fix because RLock
does not raise 'thread.error' like Lock (when releasing an unacquired lock).

datetime.datetime is required, not Zope-ish DateTime.
there is no conversion in dict anymore.

Behaviour inspired by alarms.

 unit test nature where a bt5 with a data content which is to be reindexed
is installed BEFORE the real cloudoo is setup in preferences.

In case of navigate the caller is responsible for providing date as text string.

suds library understands datetime.datetime objects, so do *NOT* convert them
to strings.

Add system preference which indicates if pre_converted_only argument should be used or not in conversion.

Add 'pre_converted_only' to ImageField which is a new way to generate thumbnail URLs
in respect to cache backend.

Do handle well case between 'display' argument and its pixel size representation by storing in cache only 'display' argument.

will read preference as it is. This can lead to a new cache key and thus a new storage in cache.

Fix Base_resetListSetting. It did not work with "Set List Setting" dialog. Now it accepts any parameters.
