1.1.0-beta.1

From the CHANGELOG:

• A new mode for ESP8266/ESP32 devices running MicroPython. This work and a significant amount of related refactoring was contributed with Viking like energy and efficiency by Martin Dybdal. This work has meant it was relatively easy to create two further new modes...
• New mode for Lego Spike devices (thanks to Chris and Ethan at Tufts University for the help and support).
• New mode for Raspberry Pi Pico (thanks to Zander, Martin and Carlos for the extensive testing).
• Updates to the Microbit mode made by Spanish source-code wrangler extraordinaire (and resident Microbit expert) Carlos Pereira Atencio. The Microbit mode now supports versions 1 and 2 of the board.
• Various bits of artwork used in the application have been updated (including a new [temporary] animated splash screen). Thanks to devdanzin for choreographing the initial work on the splash screen at short notice.
• A complete re-write of the virtualenv and third party package handlers by the hugely talented Tim Golden. This was a long term and difficult refactoring project which Tim has delivered with great aplomb. This should make package handling much smoother and simpler.
• Various smallish UI fixes, enhancements and smoothing by devdanzin. Thank you for these contributions - they really make a difference to the ease of use and friendly feel of Mu.
• This version of Mu is packaged with stand-alone installers for Windows and OSX by the wonder that is PUP - a new packaging tool by our very own Tiago Montes ~ Portugal's Premier Python Packager Par-excellence. We have big plans for PUP... watch this space. :-)
• Many many many minor bug fixes contributed by many many many people to whom we are eternally grateful.
