Sauvegarde 0.0.12

Sauvegarde saves your data in a continuous way that is to say while being written to disk. It is intended for users that have many files to save and that do not want to miss any change on them. The whole backup is deduplicated so users using many similar systems or having copies of the same file in many systems will save space regarding traditional backup. A specific feature (caching in the client) yet to implement will allow one to backup systems that do not have permanent access to the network
