Removing battery circuit

Browse Source 
Adding UMP1: 5V voltage regulator, allowing Input voltages up to 13V

Adding USB - DC jack switching circuit:
When USB cable is plugged in:
USWAA PIN1 = 0V, USWBB PIN2 = 0V, VGate Q2 = 0, VGS Q2 = -USB_5V => Q2 ON VBAT= USB_5V

When DC WALL ADAPTER is pugged in:
USWAA PIN1 = 5V, USWBB PIN2 = 5V, VGate Q2 = 5V, VGS Q2 = 0V ???, => Q2 OFF, VBAT = UMP1 out.

if plugg USB cable and DC wall adapter:

USWAA PIN1 = 5V, USWBB PIN2 = 5V, VGate Q2 = 5V, VGS Q2 = 5V ???, => Q2 OFF, VBAT = UMP1 out.
USB_5V & VBAT are isolated
