Description

During discussions regarding extending JackrabbitEventFilter an interesting suggestion by Michael Dürig came up that we could extend the JackrabbitEventFilter in oak explicitly, rather than modifying it in Jackrabbit each time we add something oak-specific.
We should introduce a builder/interface pair in oak to reflect that.
Users that would like to use such oak-specific extensions would wrap a JackrabbitEventFilter and get an OakEventFilter that contains enabling these extensions.
