wp-cli support for local machine

[EHLOVader]

Closes #563

This defines a custom wp-cli.yml for external use on the host machine.

If you have wp-cli installed locally and wanted to use it there instead of through vagrant ssh or other methods this should do it.

It accomplishes this by requiring a few php files to silence uneccessary warnings and to redefine the database for connecting from outside the VM.

So far in all local testing it has worked great.

This would be great, thanks @EHLOVader! I'm going to move it to the 1.3.0 milestone. Let's test it a bunch and get it in.

I also found out later that the internal wp-cli could be improved some by including the config/wp-cli/quiet.php itself. One poorly developed plugin in any WordPress site could turn a lovely green stream of output into a striped red mess.

I have found quite a few that throw notices and more in modern PHP releases in the official plugin repository.

You might look into this more and how it could be improved using the global ~/.wp-cli/config.yml this wp-cli.yml and possibly even a wp-cli.local.yml in each project if needed.

Finally tested it and I'm in love. Thanks again @EHLOVader, this is fantastic. 👍

You have a chance to look into those various configs you could stash in the parent folders locally and on the server? Also looking over it again the config references vvv.dev.

Did you remove the .dev in response to DNS issues in a more recent issue/PR?
