Feature #44: Image capture WebRTC & HTML5 FileIO

Silverlight was previously used to capture webcam pictures and upload
file attachments. HTML5 FileIO is now used for all attachment uploading
- including drag-drop support. WebRTC is used to capture webcam images -
this falls back to a Flash polyfill when WebRTC isn't supported.
