Made some updates to the design over the weekend to add LEDs, a nice dipswitch, make the silkscreen cleaner, clean up the pad arrays a bit and a lot more in the way of little cosmetic PCB tweaks.  Overall some very important tweaks but in the grand scheme not functionally hugely different.  Still, will make useability far better.  Some highlights:

- added power and programming LED

- added 4 user LEDs

- added dipswitch with jumpers (making it optional in event you want more IO)

- reworked the pad array and layout to make it easier to fit all of these items

- changed net assignments for JTAG signals to different header pins

- went crazy with silkscreen updates to make board easier to understand

- added some random GND and PWR jumpers to make it easier to get a scope in there and test (also PWR other "things")

Uploaded a new image of the PCB and am currently working on the second round of videos on the board.
