Removed Logging of all events...too much if jps.Debug enabled...
jpevents.lua: jps.unregisterOnUpdate had wrong name - fixed
jpevents.lua: (un)register function now return true, if the function was (un)registered
jps.lua: changed updateTimeToDie(unit) to updateTimeToDie(elapsed, unit) works, but doesn't look good
Merge pull request #308 from kirk24788/master
