Otto Blockly improvements progress #1 "DFmini Software Serial"

Hi guys good news! i just updated the MP3 DFMini block setup/init to convert into Software Serial libraries and to trigger sound events.

If you wanna try them before the new version comes (we still have a long list of things to do 馃槂) you can just simplify replace these 2 files in your local installation folders:

The blocks code update
goes here C:\OttoBlockly\www\blocs&generateurs

The English update
goes here C:\OttoBlockly\www\lang

And the toolbox update goes here
