Changeset 9919 for extensions/jiwigo-ws-api/src/main/java/fr/mael/jiwigo/dao/CommentDao.java

Message:

Complete rewriting of the api
The api now uses interfaces everywhere (for the dao, services and session manager). This allows the developer to use his own implementations if he wants.
Deletion of the singletons. There are now getters and setters. It allows to make dependency injection.
Use of sl4j in the api, instead of using log4j.
