Default menus for figures

[Rik]

3/3/17

I'm looking at resolving this bug
(https://savannah.gnu.org/bugs/index.php?50449) where the menus created for
a Qt figure are not proper uimenu objects that can be accessed by the
programmer.  The simplest thing to do is to create uimenu objects whenever
a new figure is opened.  This is already done for FLTK, so the only change
is extending it the code to run when the qt toolkit is selected.  However,
the menu options in FLTK and Qt are different.  We should consolidate and
agree on what options should be present.  That's the purpose of this
e-mail.  What do people want?
