Iterate backwards through the linked list of identically-named fields in the lua
bindings since the list is, in fact, created backwards by
proto_register_field_init(). There is some question about whether that is
actually intended, but the rest of the code seems to assume it's normal so we
will too. It was possibly a performance consideration, though that's not
well-documented if so.

Either way, this is the simplest and safest method of fixing the issue with the
lua bindings. See the bug for more analysis.
