add author parameters. set moduleversion

add author, company, and copyright parameters; with default values from
new-modulemanifest
set description for root module. this may be too opinionated
set moduleversion for resource modules as well as root
add default configuration to new resource

add a configuration block named with the ResourceName parameter

if the newly created composite resource does not have a configuration
block set, Get-DscConfiguration does not discover or import it, so we
add a new empty configuration block with the ResourceName
