Adding electrons, taus, and photons to DumpEventDataToJSON

Adding electrons, taus, and photons to DumpEventDataToJSON

For event displays, adding a couple of simple lines to include photons,
electrons, and tau jets in the JSON dumps that we hand off to Phoenix.
It's not completely clear to me if there are naming conventions within
Phoenix that need to be respected, so this mostly tries to follow what's
already done inside the code.
