Issue 37943 points out that the "customize" term
is used very inconsistently in the IDE, and it
would benefit our users if we could replace these
uses with more consistent IDE idioms.

Java classes have a "Customize Bean" item on their
nodes.  As far as I can tell, this displays a
dialog where the user can set up initial values
for the beans' properties and then create a
serialized version of the instance of the class.
This is really useful functionality, but I don't
think this is the right menu item label for this. 
A better term might be something like "New
Serialized Instance..." which then displays the
existing dialog.

For terminology details: the term Customize in the
JavaBeans spec refers to changing the properties
of an existing instance.  As such, the menu item
"Customize Bean" is probably appropriate on the
contextual menu for a serialized bean, but not on
the class of the instance.  (despite issue 37943 I
don't think the "Customize Bean" menu item should
be changed on .ser files since this is a standard
JavaBeans(tm) term.)
