build: Don't introspect ShellMenu

It is now only used internally by ShellApp to track remote actions,
so there's no need to expose it to javascript code.

-* Leave a blank line between the "class header" (Name, Extends, and other
-  things)  and the "class body" (methods). Leave a blank line between each
-  method.
-
-* No space before the colon, one space after.
-
-* No trailing comma after the last item.
-
-* Make sure to use a semicolon after the closing paren to the class. It's
-  still a giant function call, even though it may resemble a more
-  conventional syntax.
