introduce global name attribute for all types

[tomtom16]

define a name attribute, which will be available for all types.
can be a dynamic attribute which can defines a String representation of the object.
you should be able to define it yourself for each type.

this attribute will be used in spot-admin for reference mappings, otherwise the id would be used, which is kind of not readable. eg. if you want to set a usergroup to a user, you'll see a drop down field with ids of usergroups and would have to know which usergroup has wich id...
