Allow default imports in TS

[danvk]

This makes the ES6 version of the example on the homepage work:

import xss from "xss";
const html = xss('<script>alert("xss");</script>');
console.log(html);

Note that this only works if esModuleInterop is set to true, which is officially recommended (tsc init produces a tsconfig.json file with it set). You can read more about it here.

The existing type tests seemed to be broken before this PR:

$ npm install typescript
$ tsc --version

$ tsc --noEmit -p typings/tsconfig.json
typings/xss-tests.ts:9:22 - error TS2307: Cannot find module 'xss' or its corresponding type declarations.

Found 7 errors.

After it they are not:

$ tsc -p typings/tsconfig.json

The PR Quality Review check is about adding a console.log in a test file:

This is done in other test files as well https://github.com/leizongmin/js-xss/blob/b68163f444806cdb65ff64b80b0bc6c43d75d616/typings/xss-tests.ts#L16-L19

continuous-integration/travis-ci/pr is also broken on master.
