Use a default list of plugins when running "wordup init"

[stefanobartoletti]

I think it would be useful to be able to define somewhere a list of plugins to be automatically installed on every run of wordup init; usually one would use the same set of basic plugins for every project, and having a preconfigured list to use as a default would save time, instead of having to manually type each of them when prompted.

Ideally the user would be able to set this list in a global config somewhere, ready to be used when starting a new project.

Probably an even better solution would be to have a prompt on the CLI that asks for conformation to use the default set of plugins, maybe even listing them in the console for a quick review, and continuing with the default behavior of asking if one wants to add some more of them manually.

Very similar to #38

Yes, I didn't notice the other request but it seems to be the same thing
