Customize create button labels in collection

[bjarnef]

Currently create button use content type name as label.

However sometimes we may have a document type and element type witch similar name, but due the organizing of content types (or it shipping in a package) - or just because of a longer name, it would be useful to customize/override this label.

Similar may be valid for normal create dialog of content nodes.

E.g. workspace name is possible to override in content type settings.

Perhaps either an additional property on document/element type or an extension point to replace name?
