Remove prototyped services

[egeloen]

This PR removes all prototyped services & use builders to create new objects instead (It fixes #45).

Additionally:

• It removes all default values (full duplication...).
• It explodes XML services definitions in multiple files.
• It removes all configuration parameters & use addMethodCall conditionally instead (This help to fix issues with the removal of all default values).

For the Travis part, I have decided to remove the Symfony dev-master version as I can't install it (either with dev-master, 2.2.*@dev or anything else). Additionally, I have added a --no-update flag in order to not update the vendor when we require a package.

Seems good to me, aside of the my little comments. This PR will add a lot of flexibility to the bundle. Also, do you have an idea about the bug in Travis ? Seems that it fails at loading dependencies.

@mattsnowboard This PR should allow you to inject any services in your controller :)

@tmartin Can you give me your opinion?
