- Added a MssqlRepository

- Adapter some code to allow more flexibility for the new LDAP adapter from ulmus-ldap.
- Insert's fields are now escaped by default.
- A new RelationBuilder was added, a lot of code from the EntityTrait was moved into this. Some code from the Repository class will need to be moved there too.
