Subject: [PATCH] Add "toOverwrite.filters" entry as managed storage property

The new entry is an array of strings, each representing a
distinct line, and all entries are used to populate the
"My filters" pane.

This offers an more straightforward way for administrators
to specify a list of custom filters to use for all
installations.
