title: Intero doesn't find Paths-module when using cabal data files
body: <p>When I use the data-files feature of cabal, it generates a <code>Paths_pkgname.hs</code> module that lives in the <code>dist/</code> folder.</p>
  
  <p>However, intero is unable to find this file (or generate it on its own), and I can't find any means to pass an option to hint at its position.</p>
  
  <p>Note: Somewhere else (on SO?) I picked up the trick when using ghci to make a dummy <code>only-for-ghci/Paths_.hs</code> that is only brought into scope through <code>:set -ionly-for-ghci</code> being set in <code>.ghci</code>. This won't apply for intero though, as its invocation in <code>intero.el</code> specificcally instructs it to ignore the <code>.ghci</code> file.</p>
