* ./hurricane/src/hurricane :

- Bug : double deletion of ExtensionSlice, one in Cell and one in
        ExtensionGo::unmaterialize() when the last ExtensionGo is removed.
        Keep the one in unmaterialize.
    - Bug : missing "_preDestroy()" in ExtensionGo (not really a bug but may
        be useful in the future).
    - Modification : begin to uses "ltrace(level)" instead of "trace()".
        Levels affecteds to Hurricane are 0-10 (the lowest).
