[WIP] [FEATURE] Sulu Build Command

Adds builders for the `massive/build-bundle` for building the application.

e,g,

`````
# build the whole application
$ ./app/console massive:build

# build the users (and dependencies)
$ ./app/console massive:build fixtures
````

Note there are some issues, like we need to be able to pass options to the builders that are defined *by* the builders. But basically these builders work, but only in one mode (destroy everything and rebuild from scratch).
We need to add some feature to MassiveBuild to enable passing arbitrary preference, e.g. a preference to "destroy" everything, see https://github.com/massiveart/MassiveBuildBundle/issues/1
