[FIX] TextAnchor

[Lukas Renggli]

The class TextAnchor (to allow Form's and Morph's in Text) is broken
because the method #emphasizeScanner: is missing. Moreover I removed
the unreferenced and as well broken subclass TextAnchorPlus. Then I
also changed the CharacterScanner to properly render transparent
Form's. This involves 4 mcz-files all commited to the 3.9 inbox:

- Multilingual-lr.11
- MorphicExtras-lr.10
- Morphic-lr.63
- Graphics-lr.17

Cheers,
Lukas
