Disable destructive migration commands

[Igor Santos]

There are some horrible commands in the Artisan migrate package, namely refresh, that erases and recreates the entire base.

We should investigate if there's a way to intercept Artisan commands; if so:

• in development, ask for confirmation before executing
• in production, NEVER run and silently warn by email

If there's no way to directly intercept, alter the Artisan commands or even create a fork without those destructive options.
