I went ahead and made yet another revision of the board,1.3.

Changes made:

Added a plane for VCC

Added a jumper for the power LED (useful for low-power projects)

Made many pin header pads larger for easier soldering

It's looking really polished now.  The only downside is by adding a power(VCC) plane it does take some additional dwel time with the soldering iron to solder some of the pins/pads (very noticeable when I soldered the power pins on the Atmega328P, but not terrible.)

I did the two-part technique for soldering on the Atmega328P; first soldering the chip on with and iron and then adding additional flux again and going over with with my hot air station.  As Dave would say, looks like a bought one.
