Support app namespace module

[msakrejda]

I decided that I wanted my app code namespaced in a module, but the pliny generator commands don't support this. I end up wrapping things in module Foo ... end manually, and I inevitably miss something and things break. Could the generator support this out of the box, perhaps optionally?

@deafbybeheading It seems like maybe another flag to remember might be a little difficult to discover, and not too much less error prone than manually having to remember to edit by hand. What do you think?

I wonder if we could start to support something like .pliny.yaml that just remembers things like your preferred endpoint namespace and such.

@brandur that could definitely work. I agree that having a flag every time is not a great implementation.

Cool, +1.

@pedro @tmaier Any thoughts on the possibility of a .pliny.yaml? Not sure if it's overkill, but it might be a useful addition.

Could we name it .interagent.yml and save everything related to prmd, heroics etc?

Something like https://github.com/interagent/pliny/blob/master/lib/pliny/tasks/schema.rake should be then obsolete

@tmaier +1, thanks!

I think we have some higher priority stuff to get in, but let's keep this one on the back burner.
