Actifsource - #6751 [Story/Modvis] [AVME] Modvis server use customer specific config information

Release: Actifsource V11.0.0

The access to the config information which the Modvis server needs,
is now done via the 'IFileLocator', this is implemented specifically.

The information is thus made available to the Modvis server as a JsonObject.
This allows config information to be assembled dynamically.

There is an example project on GitHub:
