Implement filter-based TableViewer as a counterpart to the FilteredTree 
Projects such as PDE currently use the FilteredTree in combination with
a child-less ITreeContentProvider to simulate a filtered table.

This approach brings a big performance overhead, as the tree still has
to handle functionality such as expansion and contraction of the (flat)
tree structure which especially large trees/tables causes a significant
problems.

Not sure how to handle the API warning because the UI bundles are implementing the JFace viewers directly (just like the existing FilteredTree does).
Reason being that the filter cache is not properly cleared when e.g. a node is no longer filtered. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=187200
