cleaned up Scintilla document "updating"

 * allowed me to remove some obscure global functions and methods like
   QRegister::update_string().
 * Document updating is concentrated in qregisters.cpp now
 * also fixes some bugs introduced earlier, like undo tokens being
   generated for non-undo registers (resulting in segfaults on rubout)
