Merge latest changes from Application Skeleton

This merges the latest changes to the application skeleton in from the laravel/laravel develop branch.

This includes updates to configuration, service providers, environment bootstrapping has changed, We have a new seeding ability (provide sample data to go along with the migrations) and lots more. I have tested that all of our current changes work as far as I can tell.

Note: Please do not merge this yet. I am prepping notes to address what has changed and will update this pull with those.
