Add Helper Migrate Command

[JeffreyWay]

My generators tool, as you know, assists with the creation and boilerplate of files. After showing your plugin to people, I've already been asked about how to migrate the database from ST as well.

Can you add one more command that simply triggers a built in Artisan command? Something like:

{
    "caption": "Laravel Migrate",
    "command": "generate",
}

This command doesn't require any args. It will simply execute:

php artisan migrate

In fact, it might be nice to give users an easy way to extend this as well, without bothering you. Something like:

{
    "caption": "Laravel Migrate Rollback",
    "command_to_execute": "php artisan migrate:rollback"
}
