create bakery application based on homestead conventions

Much of the homestead user-facing conventions were kept, but the vagrant provisioning was overhauled pretty substantially to make use of a vanilla Ubuntu box and Chef to create the whole environment from scratch. The new provisioning tries to make use of Chef as much as possible to make the configuration usable in other environments (AWS for example)
