Now gencert.sh generates private key and certificate for the Secure WSS
server in a single file. This is not good to automate certification
addition to NSS databases. Generate them separately into two files and
initialize the Secure WSS server specifying them.

The command lines to generate certificate file for web server are
troublesome and their parameters confuse users. To clean up the steps per
James Le Cuirot suggestions, simplify openssl options and bash commands
in the generation script and README.

Added "Confirmed devices and distros" section to clarify who confirmed
with which device or distros bluepy-scratch-link working well. Remove
trailing white spaces. Modified git repo URL for installation.

LEGO Boost communicates with a Scratch extension through Scratch-link.
It was reported that bluepy-scratch-link fails to connect to LEGO Boost.
LEGO Boost advertises adtype 0x7 "Complete List of 128-bit Service Class
UUIDs". However, bluepy-scratch-link checks only adtype 0x3 "Complete
List of 16-bit Service Class UUIDs" which is valid for micro:bit.
To allow bluepy-scratch-link, check both adtypes 0x7 and 0x3. Introduce
constants to note those two adtype values.

As ngammarano reported in a GitHub issue, Chrome browser has bypass key
sequence to allow local server certificate. Add that description to
README.md merging jazzpecq's patch. Thank goes to the two :)

Clarify license of the bluepy-scratch-link script so that those who caring about licenses can take a look in the script code. I chose BSD 3-Clause "New" or "Revised" license, which is same as scratch-link to seek for the opportunity to get integrated into scratch-link, if possible.
It was reported that the bluepy-scratch-link does not run on Ubuntu 16.04
which has python version 3.5. The script stopped with an error about
f-format string, which was introduce with python 3.6.
Even removing f-format string from the script, bluepy-scratch-link still
requires python 3.6 because websockets module requires it. Clarify that
python version requirement to avoid confusion.

Implemented Scratch-link[1] feature as a small python script. Confirmed
it is working with Scratch 3.0[2] using a micro:bit as the BLE device to
link. This allows Linux PCs to connect Scratch and micro:bit.
Utilized bluez[3] and bluepy[4] to handle Bluetooth Low Energy connection.
Utilized Websocket module for Secure Web Socket server.

This is a minimal implementation to support micro:bit. Some of
Scratch-link features are not implemented. For example, Bluetooth (not
BLE) devices are not supported. BLE device support is confirmed only with
micro:bit.
