v19.8.7

Few PR's lots of code changes!

The big change in this release is the removal of the language parsing/formatting code and instead relies on the lingua-franca module run by the Mycroft community (and @JarbasAI in particular who set up the project originally). Much discussion is going on in the mycroft chat language channel, if you're interested join us there!

Replace language parsing and formatting with lingua-franca #2438, #2464

This basically cuts 20 000 lines of code from mycroft-core (roughly 50% of the python code). Stubs still remains to retain backwards compatibility.

Allow stop-mycroft.sh to stop Mycroft if launched through other python module #2449

This relates to the work @andlo is making to make the skills easier to run in various IDEs. Big thanks to him for improving this side of things!

Upgrade pip to latest version #2458

The dev_setup.sh script will now install pip 20.0.2, besides bringing us uptodate this allows installs on bleeding edge systems running Python 3.9.
