Modify the vue-router type declaration file and enable it to support TypeScript 2.0 complier

[ulivz]

source code: import { ComponentOptions, PluginFunction } from "vue";

This source code in the TypeScript2.0 environment will be error:
" ... node_modules / vue-router / types / vue " has no exported member 'ComponentOptions'.
" ... node_modules / vue-router / types / vue " has no exported member 'PluginFunction'.

This bug can be reproduced from this project： demo

Since I have installed Vue2.0, so I directly quoted the vuejs type file.
The most reasonable thing is to remove the coupling and make it run properly.

I think we can safely remove the comments before merging 🙂

My PR itself is not standardized, hope vuejs as soon as possible according to my PR modify the available type declaration file.

Thank you for your PR. However this actually does not solve the problem.
I've investigated it again but the root cause is that @types/vue-resource depends on @types/vue which is for Vue v1 as I said on #1170.

@types/vue has the internal module declaration in it's file like declare module 'vue', thus the TS compiler no longer search vue package even if there is a vue npm package with v2 typings. That is the reason you can load the v2 typings in that case by rewriting the module path to relative path.

The compilation of vue-router is passed by this fix but you still cannot use vue-resource because it does not augment Vue v2 typings.

Thanks for your contribution, we'll improve typings in #1685
