Added the possibility to define POD templates for any search result (Pod field with param view='search'), bugfix while getting default value for a Ref field, added Computed fields that computes a ZPT macro given as a string to param 'method', added the possibility to define a global style mapping for every Pod field, stopped to generate a field-specific set of i18n labels for pod output formats, carry portal_status_message even through page redirections, added 'deprecatedAddRemove' tags in generated configure.zcml, onEdit can now return a customized message, added possibility to normalize strings for other usages than 'fileName', in appy.shared.utils.normalizeString (for alpha and alphanum usages)
