Merge pull request #108 from adamgoose/master

Adding Provision Flag to `homestead up` command.
Fixing bugs.
Add an "artisan" list for performing migrations and database seeding as part of provisioning.
Will call "php artisan migrate" and "php artisan db:seed" on all projects listed.

Format is:
artisan:
    - project: /home/vagrant/code/path/to/my/laravel/project
    - project: [path to a second project]

Where the project paths point to the root of the Laravel project (where composer.json sits, for example).
Add artisan feature to readme.md
Indent code blocks in readme.md.
Add headings to readme.md.
Add example artisan directive to Homestead.yaml
Add composer option to run a composer install on each project to ensure we have appropriate dependencies for each project.
Modify the artisan options to allow any required commands to be run.
Update readme appropriately to cover the artisan changes and more effectively describe the composer options.
Tweak comments.
