LibraryDependencies management per project

Structure of dependencies similar to akka github project.
It's not similar in 100% because there is no need to have separate librariesDependencies per module.
It is because examples module depends on core module, so it has every of its libraryDependencies and I dont want to perform excluding.

Example:
exaples module has all dependencies of core module
core module cannot use StringUtils which can be used by examples module
