Added hibernate and Spring Data JPA to OAuth Server
Moved the hibernate dialect for SQLite to oauth-common
Required oauth-common in both resource server and oauth-server
Updated the readme for oauth-server.
Used ddl-create=false instead of ddl-auto=validate because hibernate should not validate (fails anyway).
Added the Spring Boot plugin to the resource-server.
Added Spring Data JPA and Spring Security to oauth-common.
Implemented a basic credentials object.
