Add per tick values to intel charts for ships/credits/research


Would be nice to see these aggregate statistics in addition to the tech and infrastructure statistics which make them up. They already show up on the empire report screen (at least in Proteus - I think Triton only shows ships per tick and research per tick in Triton is just science infrastructure) so having them on the intel screen would be handy for quick comparisons.


In both Proteus and Triton the intel screen stats are only sampled every 6 hours.
