Create a Henson class (java code) per source module

[stephanenicolas]

Every module S that will navigate to some other module (--> S is a source module) will use a few intent builder configurations for the modules it will navigate to.

We could create a Henson class by analyzing these dependencies, and generate class, probably using javapoet. The class will be generated in the main source tree of the source module and will allow to navigate to all target activities declared in the dependency.
