CSS modules

2.x uses vue-template-compiler, which doesn't expose non standard props (module) on <style> tag.

Should we use data-module instead or modify vue-template-compiler to expose non standard props?

I prefer the later cause scoped was removed from standard.

I assume this depends on vuejs/vue#4091 - should be included in 2.0.4

Add localIdentName support.

vue: {
  cssModules: {
    localIdentName: '[path][name]---[local]---[hash:base64:5]'
  }
}

For easier debugging.

It's tricky here. Anyway better to test a webpack generated node module?

Use vue-template-compiler built from vuejs/vue@35f145c, and remove the parser hack.
All tests passed.

Looking good. Pending 2.0.4 release of vue-template-compiler.

2.0.4 released, we can change this now
