Fixing the Failure().apply() function if the trait CommitmentStoreOperation.

See merge request !1

The function correctly created a new commitment in the FAL state but didn't
get rid of the previous one. Fixed by calling the remove() function on the
previous commit.

Incrementing version number.

Ajout d'un build.properties dans le répertoire project/ pour permettre la rétro-compatibilité des nouvelles version de sbt.
