title: atom-typescript can not find typings
body: <p>I just configured a new Angular/Typescript project in Atom using atom-typescript. The project is set up to have a main angular module file that imports all of the modules, including the type definition files. Everything compiles in gulp and runs no problem.</p>
  
  <p>Since I'm using gulp, I've configured atom-typescript to not compile the .ts files on save. Now, I'm seeing errors in all of my .ts files showing that the atom-typescript linter cannot find the typings. </p>
  
  <p>Ex: <code>Module 'ng' has no exported member 'IScope' at line 1 col 32</code></p>
  
  <p>I know that I can probably solve this problem by adding a reference path to each of my ts files like <code>/// &lt;reference path="../../.tmp/typings/tsd.d.ts" /&gt;</code>, but that seems really redundant and unnecessary.</p>
  
  <p>Since these errors are being raised by atom-typescript, is there any way that I can set the location of my type definition files somewhere in the settings for the whole project? Any other suggestions for how to handle this?</p>
