User interface tidy-ups
Add support for "gold standard" data sets to Upload CSV. These have their final weightings set to 1, which is implemented right down in the depths of the Disease Occurrence Validation Service so that data acquisition can use this feature and so that this service has sole control over the validation parameters.
Enforce case-insensitive uniqueness in the columns below. This allows case-insensitive country names and disease names in uploaded CSV files.
country.name
disease_group.name
disease_group.public_name
disease_group.short_name
disease_group.abbreviation
Upload CSV now attempts to save all disease occurrences, reporting multiple errors if necessary, rather than failing at the first error. This is more convenient for the user.
Downgrad HealthMap location validation errors to warns, to avoid spamming the system administrator
