title: TypeScript 1.6 Ionic error TS2322 Build Type is not assignable to type 'IActionSheetOptions'
body: <p>I updated Visual Studio 2015 to TypeScript 1.6 and my Apache Cordova application broke. I'm getting errors with Ionic UIActionSheet Options cssClass.  For example, the line:</p>
  
  <p><code>cssClass: "class_action_sheet"</code></p>
  
  <p>results in the error: TS2322 Build Type is not assignable to type 'IActionSheetOptions'.</p>
  
  <p>I tried to add a flag to the project file to suppress the new strictness, but either I added it wrong, or it can't be fixed that way.</p>
  
  <p>Any help would be greatly appreciated.</p>
