Woffice Updater (Unyson extension)

Files :

woffice-updater/ : the Unyson extension that you need to use in your theme's files (framework-customizations/extensions/)
server/ : the files on your server

Notes :

This is a first version
It may be better to use the functions in server/theme-updater.php in a class
It's also connected to an online service : alka-web.com/woffice-updater/ This is why there is different cases in "theme-updater.php"
