Clocks in BLIF parser. In RSavePlugin, flags to select views to save.

* Bug: In CRL Core, in BlifParser, recognize clocks (Alliance patterns).
* Change: In Cumulus, in RSavePlugin, "kw" manage a new "views" to
    specify which views must be saved. Physical by default, but sometimes
    we need logical as well. If the design contains uniquified cells,
    save the logical view.
      In ClockTree, abort the clock tree building if the design has no
    top level clock.
* Change: In Katabatic, in GCellTopology, adds 2G_5M1 configuration.
* Bug: Kite, in BuildPowerRails, if we are not in a chip the nets
   composing the H-Tree must be protecteds be blockages.
