Make registration of "Dynamic Perspective" configurable

[GoogleCodeExporter]

When integrating Jo-Widgets into the application, I would like to be able to 
disable or explicitely enable the registration of the "Dynamic Perspective" to 
the list of available perspectives as this should be an optional feature.

Requirements:
- the registration of the "Dynamic Perspective" is per disabled (per default) 
and must be explicitely enabled (e.g. setting a property) if needed
OR
- there is a mechanism (e.g. setting a property) to disable the registration of 
the "Dynamic Perspective"
