#439 Make sure that changes made by a plugin get recorded
+ simplified the change tracking for the plugins. Simply call DBObject::DBInsert (resp. Update and Delete) and the change will be recorded for the current page. This is compatible with the old (not mandatory anymore) way that was requiring DBInsertTracked APIs (resp. Update, Delete).

SetupWebPage is an alias for ModuleDiscovery and the module files should be updated progressively to invoke ModuleDiscovery::AddModule() instead.
The implementation of the module still assumes they are in the directory 'modules'... this has to be changed later to ensure the distinction between the source modules and the executed modules
