configuration is replaced by template when importing .abc files

Problem

When importing an abc file, the configuration is replaced by the one from the template

Cause

since 2121994542fdd5bbd7c2a10e354cb54cbc85f327 we paste the config from template in order to add the config to xml files. But this also happens if an abc with config is pasted

Solution

• [x] read the config from the pasted abc
• [x] if there is none, read the config from the template
• [x] apply the such read config

I reopen this. If abc file is loaded, while the konfiguration editor is open, the values of the configuration editor are used.

• [ ] switch to abc input upon importing a file.
