HAN ESP, should the PCB be updated? #50

Just a few suggestions;

Edit silkscreen so it's easier to see orientation of TSS721A
Add RX/TX/Gnd silkscreen etc to programming header
Change SW1/SW2 to Reset/Flash
Change MicroUSB to a normal barrel connector (Only Gnd and Positive is used) for easier soldering
Add 5V trace to programming pin, this way a 5V programmer can be used directly instead of both programmer and power supply separately
Replace JP1/JP2 with DIP-switches instead of jumpers

There is probably a reason why things are done the way they are, I'm just wondering if these changes could make it easier for newbies.
