Release 1.0.0 Beta 3

Changes

Command output is now a dictionary of host name -> host output object with stdout and so on attributes. Host output supports dictionary-like item lookup for backwards compatibility. No code changes are needed to output use though documentation will from now on refer to the new attribute style output. Dictionary-like item access is deprecated and will be removed in future major release, like 2.x
run_command now uses named positional and keyword arguments
