        Improved table editing: pressing delete directly before or after a table will now select
        the table first, then delete it, instead of just deleting it. Useful for when the table's
        existence is non-obvious.

        * bridge/mac/FrameMac.h: Added shouldDeleteSelection, which allows WebCore to trigger
        deletion editing deligates

        (WebCore::FrameMac::shouldDeleteSelection):
        * bridge/mac/WebCoreFrameBridge.h: ditto
