Fix missing asset

I just pulled 0.1.0 and recieved an error:

```
Sprockets::FileNotFound 
couldn't find file 'angular-rails-templates'
```

This was because the **gemspec** wasn't updated, and the vendor directory wasn't included in the gem binary.

I also undid pull #39, because it sounds like it is trying to fix the same thing, but `config.assets.precompile` has to do with what files are generated when you run `rake assets:precompile` not what files are available on the pipeline.
