#6798 [Story/TplEd] Open aggregated template function in template editor

Actifsource code generator for any programming language
Release: Actifsource V11.2.0

In the future it should be possible to display template functions in the merge editor.

This ticket serves as preparation for this feature.
Before the property 'function' in the FunctionContext can be changed from Composition to Aggregation, it must be possible to open aggregated template function in template editor.
