TextEditor class>>yellowButtonMenu (TextModel for
editing text)

���
���SmalltalkEditor class>>yellowButtonMenu��(default
TextModel, for code)

���
RubSmalltalkCodeMode class>>menuOn: (Playground)

Since we have already disabled code completion in TextModel
some time ago I would propose to set TextEditor's menu by
default, and have the Code one only explicitly (through
#beForCode which would also enable the default
codeCompletion).
Shortcuts interestingly work even without the menu, so it
shouldn't break people's workflow (e.g. you could still
inspect things and so forth).
Anyone has any objections?
