v1.3.0: Merge pull request #20 from DerManoMann/sf31

• decouple username used for auth bind from security token username; default is now the LDAP DN attribute
• fix merging of user attribute mapping
• handle LDAP attribute values that are not arrays
• Update composer.json to allow Symfony 3.1

v1.2.2: Merge pull request #13 from DerManoMann/psr_logger

• Fix LdapException handling
• Add Psr\Log dependency
• Cleanup logger handling

There is a slight BC issue here in that the logger is not automatically taken from $app any more. Instead it needs to be passed into the service constructor.
