Added support for base_url (i.e the CMS can be hosted on the root, or sub folder).

Local paths are relative to cms site url (i.e no starting slash).
Favor CMS_RESPONSE.absolute_url and url .. instead of using directly WSF_REQUEST.absolute_script_url and script_url.
Handled unicode truncation issue for logger.
Code cleaning.
