Convert RTX-Blinky from RTXv4 to RTXv5, and add UART Example

There is no example for using a UART in conjunction with RTXv5 as of this writing. This gist presents an adapted example that was tested in conjunction with Keil V5, RTX APIv2 and the Blinky example.

Create the project

Create the RTX_Blinky project in a spare directory using the "Pack Installer" button.

1. Press the pack installer buttong.
2. In the left panel, select Boards and select MCB1800>Devices>LPC1857.
3. In the right panel, select Examples, and then "CMSIS-RTOS Blinky (MCB1800)". Press the [Copy] button.
4. Select someplace to put the files. The Keil IDE will create subdirectories from this directory. Avoid using an existing location!

// Add this in your application's "payload formats" section of 
// https://console.thethingsnetwork.org
function Decoder(bytes, port) {
  // Decode an uplink message from a buffer
  // (array) of bytes to an object of fields.
  var decoded = {};

  if (port === 1) {
    cmd = bytes[0];

// this Node-RED decoding function decodes the record sent by the Catena 4450 M101 power monitor
// written in a big hurry, so no points for style

var b = msg.payload;  // pick up data for convenience; just saves typing.

// an empty table to which we'll add result fields:
//
// result.vBat: the battery voltage (if present)
// result.vBus: the USB charger voltage (if provided)
// result.boot: the system boot counter, modulo 256

I needed the list of supported languages for highlightjs, used by Markdown code fences (```).

There is a list at https://highlightjs.org/usage/, but was not readable. But it looked like markdown, so I grabbed it and made a markdown table.

Language	Classes	Package
1C	1c
ABNF	abnf
Access logs	accesslog
Ada	ada

Set up XRDP on Ubuntu 18.04 LTS

This was suprisingly non-obvious. Key clues:
