Huge repo reorganization

In no particular order...
- Created projects using F# generator, using Paket and FAKE
- Split "entities" into their own project, and created interface for
data functions required on those entities
- Renamed "data" project and used it as an implementation of data access
- Created "logic" layer that takes the data interface, and does the
non-persistence-related manipulation of items
- Moved "web" project to "app", and modified Nancy modules to utilize
Logic project and data interface instead of Data project and RethinkDB
connection
- Created test placeholder project; will be filling that out shortly
(TAD?)
