Modern British Signals (Incandescent)

Here is my own version of British Signals used throughout the network ported over from TF2. For the timebeing, it only includes left/right versions of 2, 3 and 4 aspects. More will be added as I go through them and update for TF3.

Had to remove the distant signals as it appears that Waypoints aren't supported in TF3 and were causing the game to crash.

Now also added ground position indicators for pre- and post-1960.
