[gen] Field.indexed, instead of being a Boolean, can be a str, to represent the name of a Zope Index. This way, it is possible to bypass the standard Appy choice for index types, ie for Computed fields whose content may produce any type of value; added missing translation labels in the macro displaying object's history; added default fields Tool.dateFormat and Tool.hourFormat that give application-wide default formats for dates with/without hour; added a table in Config->Users that shows the connected users and the date/time of their last access to the app; added the missing search macro for a Computed field.
