Added title attribute to avoid the following error:

ERROR in /Users/jimhartford/Sites/test-app/src/app/components/app.component.ts (28,36): Argument of type '{ dom: string; "lengthMenu": (string | number)[][]; buttons: ({ extend: string; className: string...' is not assignable to parameter of type 'Settings'.
  Types of property 'buttons' are incompatible.
    Type '({ extend: string; className: string; } | { extend: string; title: string; className: string; })[]' is not assignable to type 'boolean | string[] | ButtonSettings[]'.
      Type '({ extend: string; className: string; } | { extend: string; title: string; className: string; })[]' is not assignable to type 'ButtonSettings[]'.
        Type '{ extend: string; className: string; } | { extend: string; title: string; className: string; }' is not assignable to type 'ButtonSettings'.
          Type '{ extend: string; title: string; className: string; }' is not assignable to type 'ButtonSettings'.
            Object literal may only specify known properties, and 'title' does not exist in type 'ButtonSettings'.)
