Lazy VirtualFields for Age & Age Group added to pr_person (latter used by
Volunteer Report). Old pr_age_group field moved to
pr_physical_description.
Fix typo, tweak repr of age groups to get them sorting nicely
Fix prepop of countries & avoid exceptions in marker imports. S3Profile
supports a profile_header made use of in DRMP
