Added support for OpenID identity

Added user roles management
Improvement CMS_HOOK_FORM_ALTER design.
Factorized code into CMS_WIDGET_COMPOSITE
Use general notion of CMS_WIDGET (and CMS_FORM allows CMS_WIDGET, and not just CMS_FORM_ITEM)
Fixed various CMS_WIDGET traversal, and fixed related issue for CMS forms
Fixed CMS_FORM_CHECKBOX_INPUT when no value was set.
Added CMS_FORM_DATA.cached_value .. to pass computed values during validation to submit actions (mainly for optimization)
Added support for @include=filename  in CMS_CONFIGURATION
