HaikuDepot: Added another dummy package.
HaikuDepot: Beginnings of new TextView
 * BTextView isn't usable for what I have in mind
 * based on new TextLayout
 * completely non-functional, yet
HaikuDepot: More work on custom TextView
 * TextLayout produces some first visible results...
HaikuDepot: A round of bug fixes gets the TextView working
HaikuDepot: Fixed scroll range in ratings view

 * Due to HasHeightForWidth TextViews, the MinSize() of
   the layout has a different meaning. The reliable source
   for the actual needed height of the layout seems to be the
   Frame().bottom of the last BLayoutItem.
HaikuDepot: Corrected copyright on TextLayout.cpp.

 * The char classification stuff and can_end_line() originate
   from the BTextView implementation. Maybe Oliver Tappe is the
   lonely author of that code, but I don't feel like tracking this
   down at the moment and it should eventually be merged anyway,
   if what I did here proves useful at all.
