Allow ordering Countries
As a user, when adding/modifying to a party, I want a short list of relevant countries to select from. Currently (at the demo installation) there is a list of more than 240 countries - most of which are of no relevance for most companies. E.g. for a Germany based company chances are low we ever need to encode Afghanistan, USA or Bahamas. Instead most of the countries will be Germany of course, Austria, Switzerland (German speaking) and other EU countries.
Even if the list of countries is maintained by the admin and includes only a view countries, an order is helpful. E.g. the EU as 27 members, while the some reasons for prioritizing applies.
Acceptance criteria:
- Countries can be sorted by some priority.
- Default priority is some "middle" value, allowing for at least three higher priorities.
- In all "Country selection widgets" entries are sorted by priority
- highest priority at top
- countries with same priority are sorted alphabetically (within the priority, of course)
- nice to have: separator between priorities
