    handle invalid payloads more clearly · d988fe6e

    Currently, if you have an error in a payload module (e.g. you have a syntax
    error in a module), the error is not noticed early enough in the generation process by the parameter validator, leading to a mysterious message like so:
    
    ```
    Error: undefined method `platform' for nil:NilClass
    ```
    
    This change cleans up some of the error handling, checks to see if the payload
    module can be instantiated, and gives a more useful error output for the
    different cases. This also tweaks some of the literal string outputs to match
    other exception strings from payload_generator.
