Danilo Bargen 8e636f0d12 Examples: Clarify extern section
Some beginners are confused about the "extern" section, so I added an
explanation comment to all examples. Furthermore, using the UARTx
interrupts when UART is actually being used in the same example may be
confusing, so I changed them all to SSI0/QEI0.
