Change to MIT License

[thibaultmeyer]

Since play-ebean has been converted to a simple playframework module. It could be nice to review the used license too. Why not using MIT who is more permissive and, i think, will allow more user to contribute to this project.

What's wrong with Apache 2.0 ?

[thibaultmeyer]

This project is Apache 2.0 licensed ? I find nothing about it on source files except this following header in 1 or 2 files :

/*
 * Copyright (C) 2009-2015 Typesafe Inc. <http://www.typesafe.com>
 */

Maybe add a LICENSE file and update header of each source files ?

Apache 2.0 seems a good license too, more retristrive, but good too.

Actually Copyright != License. Yeah this project misses License.txt, but under maven central you see the Apache 2 license.

Added LICENSE file to make it easier to find licensing. See adb3820
