* attachView() is now called _CreateSelf() and creates the app_server
view counterpart for itself, and no longer for a child view.
* removed superfluous deleteView().
* moved drawing from BWindow::DoUpdate() to BView::_Draw().
* made the recursive hook call functions consistent.
* fixed BWindow::DispatchMessage() to send public messages to the intended
target (instead of always handling them itself directly).
* DispatchMessage() no longer eats unmapped key events that were targeted
at the window directly.
* B_KEY_DOWN and B_KEY_UP events are now send to the target view as well
(this couldn't work before as BMessages were broken with B_PREFERRED_TOKEN).
* the default button is now correctly targeted by BWindow::_DetermineTarget()
(previously, the enter key was hacked to get through via _HandleKeyDown()).
* removing a view now also makes sure it won't have focus any longer.
* also, the DetachedFromWindow() hooks are now called first, so that any
changes made there cannot mess up our window anymore.
* removed BView::SetPattern(); _UpdatePattern() now does its job.
* renamend private methods to match our preferred style.
* removed unused methods and variables.
* more consistent naming overall.
* removed _PR3_COMPATIBLE_ stuff - there is definitely no need for us to be
compatible to that one.
