Guide Feedback: Inline declaration of "leds" removal

Per Ladyada - guide feedback to review:

`In the keyboard converter sketch, remove the inline declaration of "leds" ["uint8_t leds = (caps | (num << 1));" to "leds = (caps | (num << 1));"]
and declare "leds" at top of routine as "static uint8_t leds;"

Now LEDs work!`
