Added code to sort config parameters

With these changes, the configuration files are saved (as YAML) in a key-sorted order (before this set of changes, they were saved in a semi-random order based on the hash-map used to store them)
Added code to sort config output

With these changes, the configuration is output by the config slice in a key-sorted order (with the "@noun" key removed).  This makes it much simpler to find the configuration parameter you are interested in; prior to this set of changes, the configuration parameters were output by the config slice in a semi-random order (based on how they were inserted into the hash-map used to store them) making it very difficult to find a specific configuration parameter.

Merge pull request #55 from tjmcs/tb/return-help-from-config

Fixes #50 (config slice does not return help)
Fixes #35 (handle missing Hanlon server properly)

The changes in this commit ensure that an understandable error
is output if the CLI-based client is run while the Hanlon
server is not running (or is inaccessible at the URL that the
client is attempting to connect to based on its configuration).
This commit also includes a small fix to avoid "null" values
being output in the help messages returned by the config slice
when these new errors are thrown.
