Added zillions of #if wxUSE_XXX

Removed cmndlgs usage of wxSizer and constraints
  Changed occurences of wxConv_xxx to wxConvXxxx and
    changed some wxConvLibc to wxConvCurrent
  Added Unicode tests to typetests (not finished)
  Compile fix for wxString in Unicode mode - we have
   to use the "experimental" printf then, I guess.
