Added delete token as noted here

Are you sure this should be under meta.export.js?

This rule is for var, let... in named exports:

export var x = 0;
export const CONSTANT = 0;
export let scopedVariable = 0;
export function func(p1, p2){}
export class Foo {}

btw, I moved these lines up in #276

Ok, thanks. I didn't notice that this rule as a whole was for exports.

Sorry, I wasn't clear. export delete is not legit
