QuasiQuoter for non-interpolated strings, texts and bytestrings.

The s quoter contains a multi-line string with no interpolation at all:

 {-# LANGUAGE QuasiQuotes #-}
 import Data.Text (Text)
 import Data.String.Quote
 foo :: Text -- String, ByteString etc also works
 foo = [s|

Well here is a
     multi-line string!

|]

Any instance of the IsString type is permitted.
