Moved all the redirection methods from LeoQtBody class to the attic.  All tests pass.  Hooray!
Added 4 do-nothing methods to the base LeoBody class as documentation and to silence pylint.  These are *not* redirection methods!
This required a dozen or so changes to Leo's core, and one in unitTest.leo.
Most changes actually cleaned up the code: they typical pattern: w = c.frame.body.wrapper.
