Summary: Various Console fixes

Initial Comment:
The attached patch should fix most of the problems that
occur when the Console buffer overflows and wraps back
to the start and some related issues:

* new lines are now cleared
* scrollbar now works correctly after a wraparound
* home/end now move the cursor to the start/end of the
current prompt
* shift+home/end move the window to the top/bottom
* shift+pageup/pagedown move the window up/down a page

I renamed the function updateScrollBar to
updateScrollBuffer because it now also updated some
state not directly related to the scrollbar.
