Fixed and enables the old wakes. Enabled the fps counter by implementing the team-27s fps counter from their code, fixed trails from starting at the start of the startline no matter at what point in the race the stream is connected to (this is means the map starts a lot cleaner). Added live tracked speeds which are taken from the boat location packet. Linked the speeds coming in to their specified boats and allowed the onscreen speed tracker to keep up with the speeds. Linked the current speeds to the wakes so the wakes are redrawn for each change in speed and size to match the speed. Also added the toggle functionality back to the fps counter so they can be toggled on an off.
