Generate type Day instead of Date and import Day from package time module Data.Time.

There are more errors after the date thing. See: https://github.com/haskell-servant/servant/issues/1084#issuecomment-439507900 I'm not sure if you still have this issue. I'm working on a fix that would address this and a few other issues with the servant generator. Current progress here: https://github.com/adamConnerSax/swagger-codegen/tree/UpdateHaskellServant It compiles now, but I have yet to test the result. I'll update here once I do.
