Matt Low dce62e7748 Set config defaults using a "default" struct tag
Add new SetStructDefaults function to handle the "defaults" struct tag.

Only works on struct fields which are pointers (in order to be able to
distinguish between not set (nil) and zero values). So, the Config
struct has been updated to use pointer fields and we now need to
dereference those pointers to use them.
