[!!!][BUGFIX] Fluid Widget Links: Do not use cHash by default

When using the widget.link viewhelper, it is not possible to create links
without cHash.

In order to achieve this, cHash is only appended, if "useCacheHash" is
activated (addQueryString is always added, which makes sense due to the
parameters for the link).

As this is a breaking bugfix, it can only go in master.
