Implement console client

@Scarygami the generator should now create console based apis. I changed the pubspec format around a little. Now the name is `<api name>_<version>_api`. If you want to give one of the API a spin before the oauth stuff is merged you can do something as follows with the dependencies in the pubspec file. 

```
name: drive_v2_api
version: 0.0.3
description: Auto-generated client library for accessing the drive v2 API
homepage: https://github.com/dart-gde/discovery_api_dart_client_generator

dependencies:
  js: '>=0.0.14'
  # google_oauth2_client: '>=0.1.0'
  google_oauth2_client:
    git:
      url: git://github.com/financeCoding/dart-google-oauth2-library.git
      ref: oauth2_console
```
