Users can now retry failed uploads.
Fixed KamcordCallbackInterface callbacks for KamcordViewDidAppear and
KamcordVIewDidDisappear so they are no longer called when the movie
player appears/disappears. They are now only called when the view is
presented for the first time and when the [Done] button is actually
pressed.
Added #if UNITY_IPHONE guards to Kamcord scripts to not interfere with
Android builds.
Removed .meta files when copying files from Unity to Xcode project.
Fixed crash in KamcordThumbnailTextureObject.cs.
