title: TypeScript include non .ts files in compilation directive
body: <p>For some reason only .ts files are included:</p>
  
  <pre><code>{
          "compilerOptions": {
              "module": "commonjs",
              "target": "es6",
              "noImplicitAny": false,
              "sourceMap": true,
              "outDir": "dist",
              "baseUrl": ".",
              "types": ["node", "mocha"],
              "paths": {
                  "*": [ "src/main/*", "generated/*" ]
              }
          },
          "include": [
              "**/*.yaml"
          ],
          "exclude": [
              "node_modules",
              "dist",
              "build"
          ],
          "compileOnSave": false
      }
  </code></pre>
  
  <p>Why is it not picking up the yaml files? They are needed for my Swagger API spec.</p>
