When you press the Esc button in an MVC workspace,
you get a walkback 'offerMenuFromEsc: not understand'. 
In Morphic, the context menu is offered when the Esc button
is presssed. This change set adds the same feature for MVC.
(I simply added the missing method to the instance
protocol of  ParagraphEditor.) 

Until now, the method was only implemented in TextMorphEditor, 
a direct subclass of ParagraphEditor. 
The method selector #offerMenuFromEsc: is registered in the
class variable CmdActions of ParagraphEditor as handler for
the Esc character. Earlier versions had the following handlers
for Esc: (see versions of
ParagraphEditor class>>initializeCmdKeyShortcuts)

#selectCurrentTypeIn:   (sma 12/15/1999)
#escapeToDesktop:   (di   12/3/2001)
#raiseContextMenu:  (dvf 12/7/2001)
#offerMenuFromEsc: (sw 12/7/2001)

All these are defined in ParagraphEditor.

I should add that there are two ways to describe the bug:
1. A method that is registered in  CmdActions  was not
   implemented. My proposed fix is based on this description.
2. Class  TextMorphEditor  needs a handler for  Esc  that
    is not needed in the superclass, but the handler was 
   erroneously registered in a class variable of the superclass.
   This error description implies that  TextMorphEditor  should
   have a collection of its own to register handlers for special
   characters.

What is the preferred bug description? Opinions are
welcome!

Grretings, Boris
