API calls that return lists now take limit, offset and reverse params.
API calls that used to return data & optional list (e.g. blockWithTransactions)
now only return base data. The optional lists can be fetched via
a different API call.
Also: SLF4J now routes logging to log4j2 so start up output cleaned up.
Suppressed extraneous Jersey warning about Providers during start-up injection.
