Include "size" in /arbitrary/resource APIs

Note that this is not always accurate - it relates to the largest transaction size for this name, not necessarily the latest or the combined size of multiple transactions. This can be made accurate as soon as we have a "Resources" table to store this info. Trying to do it before then will be too inefficient in terms of queries.
