Create a feature that analyses the templates and validates if they are using deprecated mappings.

Add to Xporter an automatic (when installing Xporter) or manual (have an option in management templates) functionality that would validate if the mappings used in the model were updated or belong to the discontinued list.

This will ensure that we create new mappings and know that they would be implemented. If we change a mapping, it is to improve performance or bring more specific information and consequently, we can gradually eliminate outdated mappings.
