IDE w/ LPC824, part 2

Let’s get that upload going. Remember, this is about adding a “hardware platform” to the Arduino IDE so it can compile and upload files to a Tinker Pico, based on the LPC824 µC. There are two parts to this: 1) getting all the IDE setup files right so that it knows how to compile & upload, and 2) implementing pinMode(), digitalWrite(), etc. so they can be used with LPC824 microcontrollers in the same way as with ATmega’s and other µC’s.
