Table controller

This is the first of many pull requests.  I am separating out the work that I did on migration files.

Working with the Tables Controller made me realize that we are working to set a restaurant id to things that should have them automatically applied (at the model level).  This will hopefully lighten the load on our controllers
>Maybe we can utilize the same method for creating connections with reservations and users...

The deleted migration files are redundant because we add and remove the same column twice.  This just reduces overall package size.

Also, I began work on the admin/tables view.  I think this view can be manipulated into the restaurant floor layout.  I am doing more investigation into the topic with the ActiveAdmin docs
