The SkinVector implements IContextSource, thus it has to provide
the getConfig() method. Vector skin is currently using
it's own `vectorConfig` in one place and it passes the VectorConfig
to the VectorTemplate class. Sadly the VectorConfig is the same
thing what $this->getConfig() provides. There is no need to make
this code more complex by handling two different config containers
which at the end are the same GlobalVarConfig instances.
If we decide to handle VectorConfigs differently, let's thing it
through, for now we should simplify code and remove all uncessary
logic. Thanks to that, there is also no need to override the
setupTemplate().

With this change the constructor of the parent class gets called like if
there is no local constructor. This allows the ancestor classes to
initialize themself in their constructor.
