Filter recursive

Well, well... Recursion isn't that bad at all. Filter experimental
ArchiveView recursive by the following rules:
* check children _and_ parents for filter
* if any child _or_ parent matches, accept the current row, parents and
children.

The column is converted to a QString and matched by QRegExp, so don't
try to match numbers or anything else.
