newRPL - build 1255 released! [updated to 1299]

[mbarnes]

I was able to get newRPL working tonight using a new Ubuntu 16.04 installation running under VirtualBox.
When I followed the instructions correctly, I had no problems. A couple of observations and a question:

1. In the Wiki, in the 'Build from Source' section, under 'Building the Desktop Simulator', the first line
references 'newrpl-comp.pro' and it should be 'newrpl-ui.pro'.
2. When compiling the firmware, I ran into the classic 'sys/cdefs.h' not found problem. Installing
'libc6-dev-i386' solved this. You might add that to the Ubuntu dependencies. It is not needed unless building
firmware.

Question: I am using an HP 39gs as my newRPL platform. Under windows 10 I was eventually able to load the
firmware onto the calc. How do I now update it? The usual trick of 'reset button/+ - keys/3 seconds' doesn't work
and the Windows Calculator Connectivity Kit doesn't recognize the calculator with the new firmware.
What is the recommended method of updating 39gs firmware with a newer one? Thanks!
