2b46b7e889 many more const decls 
ruby gobject-introspection is quite fussy about needing a lot of const
declarations ... these changes help vips_image_matrix_from_array()
appear in Ruby

64d081e726 return default value for unset props 
we used to issue a warning and return early, but this can leave garbage
in the *value pointer, I think

ruby gobject-introspection will walk object props during GC and can see
state inbetween init and build when not all objects have been given a
value ... we don't want these warnings

fbe321eebf change exif names argh 
change exif names again: we were storing under @title, but that's both
subject to i18n, and unlookupable in libexif

we now use @name, which is not subject to i18n and can be searched for
... this will break most code which expects certain exif tag names

also, when we update exif, allow any tag, not just updates to existing
tags, see:
