Script descriptions per projectType

[AWolf81]

Describe the bug
During my work on #292 I've noticed that Next.js is adding a script with the name start which is used for a different purpose. It is not the development server. It's the server to serve the production build locally.
The development server script is called dev.

This issue needs to wait for the mentioned PR.

To Reproduce

1. Create a new Next.js project and have a look at description for start script
2. Create a new CRA project. It will have the same description for start script

Expected behavior
We should have a naming that's more specific to each project type.

I think we have two options to solve this:

1. Create a new reducer project-description.reducer and store the description on the redux state. e.g.

    { 
      'create-react-app': {
         start: 'Run a local development server',
         build: 'Bundle your project for production',
         test: 'Run the automated tests',
         eject: 'Permanently reveal the create-react-app configuration files',
         format: 'Runs a formatter that tweaks your code to align with industry best-practices'
      },
      gatsby: {
        // same as CRA - duplicate string here
      },
      nextjs: {
        start: 'Starts the application in production mode',
        build: 'Bundle your project for production'
      }
    }

2. Add the description to a config file

Environment:

• OS: all
• Version: master
• Node version: -

Things to discuss:

• Do we need this description on a per project basis? That would be needed if we want to implement custom task descriptions per project.
• Is it OK to store the description in state? If we want the description project specific maybe we need to store it in a guppy configuration folder e.g. .guppy and save it in a configuration file. This would also allow us to move the guppy stuff from package.json to a configuration file inside .guppy

OK, I'm working on this.

I think the .guppy config file can be added later. I'm adding the project task descriptions to src/config/project-descriptions.js - I think it's not needed as a reducer as it is just an object literal constant.
