Add easy-deploy option when installing the template using Vue CLI

[codetheorist]

Add an option to the template installer that allows the user to add easy-deployment for GitHub pages.

If the user opts-in to this option, they will then be presented with 2 further prompts for:

• Branch Name
• Base URL (for project pages)

Once these details are entered, the will then simply have to run npm run deploy to deploy a built site to the correct branch of the repository.

Hi there.

This is a feature I find doing myself a lot and I'd love to have here on this template.

Mind if I ask if there'll be any progress in this issue or, if that's the case, could I take over it?

Edit: I did some digging. Seems that @vue/cli@3 is the new way. I'll look into that.
