keyboard duinoedu

hi david
it s a test of pull request
i ve made 2 block in utilities for keyboard
and 3 block for duinoedu

all those block need librairies in arduino.
there is no one comment for how to find the librairies.

my friend also work on making block
i haven t test the block duinoedu block with real block
but apaprentli to the code generate, it should work fine.
i ve test the keyboard block
but in the code generate in arduino, you should have a  keyboard.begin insteed of  keyboard.brancher
unless you will have a french keyboard

in git for commit, its $git commit -a
thanks for the information for commit
