Improved Hurricane/Python database reset.

* Change: In CRL/helpers/__init__.py, to ensure a complete restart of
    the database the __init__.py must be called again, but it's not the
    case with reload() (see Python doc). So helpers.resetCoriolis()
    must explicitly removes the Coriolis related Python modules from
    sys.modules (calling "del sys.modules[moduleName]").
      That list of Coriolis Python modules is built by calling
    helpers.tagConfModules(), it will tag all modules added to
    sys.modules since startup. It will remove (much) more than
    Coriolis modules, but that should be ok.
* Change: In CRL/etc/{node*,symbolic}/TECH/__init__.py, add a call to
    helpers.tagConfModules() for the techno modules to be erased on
    reset.
