REVISION SUMMARY
  The new connect syntax has several advantages over the old syntax:
  
  (a) Connecting with the new syntax is faster;
  (b) It is compile time checked.
  
  There are still a few places where the old connect syntax is used, e.g.
  connecting to QML buttons in the Desktop Grid effect.

TEST PLAN
  Have been testing this patch for ~2 weeks, haven't noticed any
  regressions.
