Textual editors reference method signatures by only their name (i.e., their parameter types are ignored)

The following applies both to the textual repository and usageprofile editors: When referencing signatures, e.g., when specifying the target of an ExternalCall, method signatures are currently referenced by <interfaceRequiringRole>.<signatureName>. Thus, methods with the same name but different parameter lists are currently not distinguished in the textual editors.
