Added code for version check in DB Monitor.
Merge branch 'master' of https://github.com/deerwalk/voltdb
Passed admin=true while calling API only when the security is enabled.
We made this change because we were getting following error while calling
API with admin=true.
{"status":-3,"appstatus":-128,"statusstring":"port out of range:-1",
"appstatusstring":null,"results":[]}
