Configuration model updated from connector code doesn't reflect on MartServer

[cgourdin]

If entities on configuration model is added by connector code, the configuration is well updated on MartServer but not on referenced entities user map (why : Reading entities by Map is more efficient than for each resources/links tree).

610842f is a temporary patch, to enable total configuration updates by connector and manage optimized access on entities map, an listener class must be developed and join on adding entities and remove entities from configuration model.
