Emission Factors - Add location

[ben3474]

When loading the emission factors add the ability to define the region it applies to. Create 2 new fields country (res.country) and country group (res.country.group) where only one or the other can be fed. For each field only one value can be selected (one country or one group of countries) The section encapsulating these 2 fields will be named "Geographical scope"

This issue does not deal with the data loading, only the UI and the data modelling.

At this stage we do not deal with geographical scope being more granular than countries (eg regions/cantons...)

• create m2o in EF table towards res.country and res.country.group
• display both in xml: en dessous de Uncertainty et required types Country et Country group sur la même ligne. Possibilité de rechercher/regrouper dessus depuis la list view. Mettre le tracking sur les champs
