since this param may be null, please name it |opt_resources_lists| or something
to indicate its not required

[jungkees, 2015/06/06 13:55:11]

Renamed it |opt_resources_list|. Note that I found resources_list is more
relevant than resource_lists as other param definitions are already using
resources to refer to the vector of ResourceRecord. Corrected the related param
names in service_worker_storage.h/.cc as well.
