Compilation is OK but this version hasn't been tested

        * GSWeb.framework/GSWFileUpload.m: Added Traces
                corrected bug when uploading string type data.
        * GSWExtensionsGSW.framework/GSWFileUploadFormComponent.m:
                handle nil fileInfo retrieving, added isDeleteEnabled
        * GSWExtensionsGSW.framework/GSWFileUploadFormComponent.gswc/GSWFileUploadFormComponent.html/.gswd:
                added isDeleteEnabled condition
        * GSWAdaptors/commun/GSWConfig.c/.h: added adaptorTemplatesPath handle (per application and global)
        * GSWAdaptors/commun/GSWApp.h/.c: added pszAdaptorTemplatesPath
        * GSWAdaptors/commun/GSWHTTPResponse.c added parameter to GSWTemplate_* calls
        * GSWAdaptors/commun/GSWAppRequest.c added parameter to GSWTemplate_* calls
        * GSWAdaptors/commun/GSWTemplates.h/.c: added GSWApp* parameter
                o handle per application Templates
        * GSWeb.framework/GSWResourcesManager.m: traces
        * GSWeb.framework/GSWApplication.m:
                o change trace level from "low" to "application"
                o added filterLanguages: method
        * GSWeb.framework/GSWContext.m: added filterLanguages: call in _languages
        * GSWeb.framework/GSWAssociations.m: traces
        * GSWeb.framework/GSWSession.m: Added Traces
        * GSWeb.framework/GSWUtils.m: Added warning
