Migrated users to userbundle, and entity based namespace
First attempt at providing WSSE authentication.
The implementation is the one from the Symfony2 documentation (http://symfony.com/doc/current/cookbook/security/custom_authentication_provider.html)
Re-added missing use of Post annotation
Added dependency on LiipFunctionTests bundle
Updaed Symfony
Added registration code, as well as an attempt at user authenticaion code.
Authentication currently fails, since the firewall locks out the request.
Should be further investigated.
WSSE auth test working
Added test for failing password
Added tests for failed authenticatioN
Changed from storing nonces on the filesystem, to storing them in the database.
When on the filesystem, the base64 of a nonce could contain special chars, like /, which messed up storage. The DB is not susceptible to this.
Moved validation of expiry of the nonce to the entity
Removed old and too new PHP versions
Cleaned up UserController, the return statement was never reached, and the else was superflous.
The postUserAction method was a placeholder during testing
Changed auth mechanism to be 'two-step'.
The client requests authentication from the /user/auth route, using the user's password as the secret.
This will, in time, create a session key, which can then be used for future authentication of the user.

Only the session password should give access to functionality, the user password only gives access to generate a session password.
This means that the user password, even though it is hashed, will only be sent over the wire as few times as possible.
The session password can be changed whenever necessary, the client just has to re-auth to get a new password if it is compromised
