S2m

Analog writes no longer flash but stay steady.

This release requires that the micro:bit be flashed with the latest script [s2mb_min.py](https://github.com/MrYsLab/s2m/blob/master/s2m/micro_bit_scripts/s2mb_min.py)

This release revised the s2mb.py script to resolve issue 17. Flash the[ minified version of the script](https://github.com/MrYsLab/s2m/blob/master/s2m/micro_bit_scripts/s2mb_min.py) to the micro:bit.

A fully commented version of the micro:bit script may be found [here](https://github.com/MrYsLab/s2m/blob/master/s2m/micro_bit_scripts/s2mb.py). Only flash the minified version, since the fully commented version will not fit into the micro:bit.

The only change for this release is the micro:bit script. All other code is the same as version 2.3.

There are no other changes other than the addition of the demo for the Brazilian Portuguese language.

Scratch blocks for Brazilian Portuguese can now be automatically selected by typing:
s2m -l 5

This version added the new block translation and updated the version of s2m to 2.1.

Pypi is having issues with release numbers so bumped to 2.0
