Move menu/key binding code from Bindings.py to EditorWindow.py,

with changed APIs -- it makes much more sense there.
Also add a new feature: if the first character of a menu label is
a '!', it gets a checkbox.  Checkboxes are bound to Boolean Tcl variables
that can be accessed through the new getvar/setvar/getrawvar API;
the variable is named after the event to which the menu is bound.
