Prepare for a FreeRTOS V9 release candidate:

- Remove the standard demo files that used the [long since deprecated] alternative API.
- Add standard demo task that tests the new xTaskAbortDelay() function.
- Update the Win32 Visual Studio project to use Visual Studio 2015 Community Edition.
- Rename the xGenericListItem TCB member to xStateListItem as it better describes the member's purpose.
