Subject: Auto-redact - First stab

Add a SfxRedactionHelper::autoRedactPage method which searches for the given term
through the gdimetafile which has the whole content of an xPage (a Draw page),
and draws redaction rectangles at proper positions with proper sizes.

The search is case sensitive, and finds only the first occurences on a line.
Will switch to a proper search provider via a follow-up patch.
