Mike Kaganski acbb6c98ae tdf#160867: restore HTML map export for text hyperlinks in frames
The most exciting was to discover that this functionality was actually
already implemented prior to 2001, and then accidentally dropped, and
nobody noticed, until Noel did his great cleanups, and made an amazing
investigation in commit ed2ae3c3bb (remove
dead SwNoteURL, 2018-03-14). The detailed commit message made my task
so much easier: I knew where and what to restore.

So this change restores relevant pieces removed over the time in commits
* 1b666235f6 (loplugin:singlevalfields
  improve copy constructor check, 2018-01-03),
* be8c414567 (loplugin:unusedmethods also
  check for functions returning bool, 2018-01-19),
* 73139fe600 (loplugin:unusedmethods,
  2018-01-20)
* bb7ade140d (loplugin:unusedmethods,
  2018-03-08),
* ed2ae3c3bb (remove dead SwNoteURL,
  2018-03-14),
* fd1cfd25b4 (PortionType::Url is unused,
  2019-01-18).

It re-implements the functionality accidentally removed in commit
da7671e4f7 (Opt.(FME): The new attribute
handler makes a lot of code superfluous, 2001-03-15), moving it into
SwAttrHandler, which replaced the ChgFnt in SwTxtAttr.

It also fixes the code writing the HTML image map, to output valid HTML.

And finally, it adds a unit test, to avoid repeating the story :-)
