[INTERNAL] Add possibility to customise produced archive folders structure

[jguidoux]

The default archive folders structure is :

/
|___ bin/
|___doc/
|___doxygen/
|___headers/
|___lib/

Add the possibility to the user to change. Maybe with a map like this in the build.gradle.

cpp.archivesFolders [headers : "include", LIB: "libraries"]
This must product this structure :

/
|___ bin/
|___doc/
|___doxygen/
|___include/
|___libraries/

**Caution**, changing the archive structure can broke the dependency management system. Before implementing this feature ask if it is really a necessary feature ?
