Pass arguments to agent/agent.py info when using bin/agent and bin/info.

Fixes #506.

As far as I know, the only argument that a user would want to pass when using ```bin/agent info``` or ```bin/info``` is ```-v```, which will be sent to ```agent/agent.py info``` to tell it to display tracebacks for check errors. Can somebody who has a little more insight into how these scripts are used correct me if this assumption is false?
