Now pre-compiles age group metadata instead of generating it on every query (#235)
* Server will now quit on start up if schema updates fail (closes Abort start up if an error occurs during database upgrade #221) * Moved AgeGroups to it's own class * Improved query performance by defining the AgeGroupId as a metadata item. A metadata refresh is required to generate this data
