Added 'given_command' to local() 'out'

This makes adds the 'command' attribute to local()'s return, as
in run() and sudo() to make the initial command accessible after
execution.

Inspired by: [Python Fabric NameError: global name 'log_action' is not defined](http://stackoverflow.com/q/22696486/4279)
