Added Preliminary Test #7 (Caching of the Db request) and concurrent generation of Random Ids.
Updated the Amazon Web Service Dependency to the latest version.
Added SQLite Database Provider and refactored AppSelfHost out of AppHost.

Additionally, added logic to only include routes for databases that did
not produce an error when Service was initialized.
Fixed issue in UpdateWorlds  where Update used when it should be UpdateAll.
Removed the SQLite Database provider

Removed the SQLite Database provider as it is not a good real-world
representation and if run as an in-memory database, must maintain a
persistent connection. Also updated README.md file to not mention SQLite
as a test scenario.
Merge pull request #410 from KevinHoward/master
