Add support for resource action descriptions

This will allow us to generate better documentation by including
action descriptions in the resource help, and includes updates to the
resource inspector and doc generation task to include action descriptions
in resource action data.

This change permits actions to be defined with the optional new
'description' parameter as follows:

```
action :my_action, description: "my_action changes the state of this world"
...
end

Action description can be looked up using the
`.action_description(action)` method of the resource class.  Action
descriptions are inheritable and overridable.
