Merge #337
337: Examples: Clarify extern section r=korken89 a=dbrgn
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.
