Text Editor: don't force other views to follow the cursor

While the existing behavior worked as intended,
it wasn't possible to have two views on the same file at different
locations.

Since there isn't much use in having two views open at the same location
allow one view to be at a different scroll location.

UI edit-source and selecting a text data block now need explicit calls
to scroll to the cursor location.
