Feature: Filter not Generated Component, but underlying BeanItemContainer (or else)

[datenhahn]

It should be easy to add filters which filter not on the component (which does not support filtering), but the wrapped containers property which e.g. is a string.

Here you find a working example how it can be done manually:

To complete this feature convenience functions are needed to make adding a filter more easy.

Another simpler way maybe to access the underlying container as a Property. Then I can add my container filter.
