First code commit:
- Maven POM importing Spring Boot, Spring Data JPA and H2 database.
- H2 database is actually located in your ~/tmp/h2.db
- Created Marker and Server entities.
- Created Server (dummy) controller.
Added server repository.
Updated JPA annotations in entities.
Thinking about integrating Spring Shell to use the application from the server CLI (ssh).
Implemented all Admin functionalities for the Servers.

- Admins now interact with REST Controllers, as will the mod
	- Could not integrate a shell for the admin operations (spring-shell or integrated shell)
- Implemented a master key (created at each application start) for admin operations
- Using an in-memory H2 database for development
- Implemented List, Create, Rename, Change Key and Delete Server.
- Controllers return OperationResult objects in JSON format.
Implemented Markers operations (List, Add, Edit, Delete).
- Added DS_Store files to .gitignore
- Moved packages into "src/main/java"
- Updated ServerController to accept some parameters as POST params
- No unit tests yet, will come later. (Need to read and test things before)
