Documentation flaws which make readers confusing

[boxsnake]

I noticed that in the documentations, there are some flaws which make readers confusing.

1. In github's documents, it uses filter(params) format, while in NPM documents, it uses filter params. I tested in Vue 2.x.x, only filter(params) works. I think the documentation differences will make user confusing.

2. In both Github and Npm documents, it says Vue.install(VueFilter) to manually install this filter bundle. However, when I tested in Vue 2.x.x, install is not a valid function of Vue, users should use Vue.use(VueFilter) instead.

@boxsnake I update README last time, but I don't publish it on NPM, so there are some difference. thanks for you remind, I will publish the change to NPM soon.

does this supports es2015? like "import filters in 'vue-filter'" ? Vue.use(filters), and then how to use it in components?
