title: Long-Press spark.components.list Item
body: <p>Does anyone know if there is any sort of Long-Press gesture (like on Android) in the new version of flex? </p>
  
  <p>I'm looking to make an item in a list editable/delete-able upon long-press, but I'm really hoping I wont have to make my own Long-Press gesture with a timer and whatnot. </p>
  
  <p>If there is none built in, does anyone know of any resources/blog posts about how to make a Long-Press gesture - or, furthermore, how to make an Editable list?</p>
