Refactored CMS_MODULE.router (..): WSF_ROUTER design, to create only one router object of type CMS_ROUTER. Added optional CMS_NODE.link: CMS_LOCAL_LINK Reviewed permissions related to node module. Refactor and add CMS_STORAGE_SQL(_BUILDER) abstractions for implementation relying only on SQL statements. Factorized sql builder initialization (to work for sqlite and mysql storage builders). Added CMS_RESPONSE.formatted_string (a_text: READABLE_STRING_GENERAL; args: TUPLE): STRING_32 Added function "translation", but not implemented for now. Updated indexing notes and comments. Code cleaning.
