Update types of event/run/lumi in Jet/MET (for fastjet)

[StoyanStoynev]

The online is changing to produce data with event numbers that are 64 bits instead of 32 bits. CMSSW software needs to be modified to handle that. Following

I am making changes to different packages, here JET/MET for fastjet usage. Changing the types in fastjet would be a longer process so I just explicitly cast to the supported type (the run/event numbers are used as random seeds - there should be no practical problem here). Updates are generally trivial and there should be no any visible effects of them (except for the rare event numbers with > 32 bits).

I tested f73f9a9 on top of CMSSW_7_3_X_2014-11-04-0200 - no diffs (despite some variations seen in jenkins) and none expected.
