Subject: [PATCH] rust: Highlight function signatures as functions (#4073)

This stanza highlights functions within trait definitions. For example,
in:

    pub trait Widget {
        fn render(self, area: Rect, buf: &mut Buffer);
    }

`render` is currently highlighted as a variable. With this change it's
highlighted as a function.
