Implementing, connecting & configuring the ESP!

[Xasin]

This PR contains pretty much all necessary code to properly communicate between the ESP and AVR ESP->AVR is tested, AVR->ESP still needs the receiving code, but that should be fairly easy :3

Also contained is the schematics change to the Lasertag set required to use the UART, as well as necessary pin changes etc.

I /should/ have put the Fresh_IR PR to main, but ... It's in here now, so whatevers :S

          RXEndpoint = RXEndpoint->nextEndpoint;
          if(RXEndpoint == 0)

That needs to be moved upwards, else having no Endpoints might crash. Silly, yes, but a potential problem.

  if(tempOCR1B >= FRAME_TICKS)
      tempOCR1B -= FRAME_TICKS;
  OCR1B = tempOCR1B;

Flip these around >.> If not, there is a brief window for OCR1B to generate a match interrupt before the new value is set. Rare, but hey, can happen.

              RXCallback(*(ShotPacket *)&data);

Callback needs to be called AFTER the checksum has been confirmed! Yikes :S
