New DataBase::getCell() and bug in Technology::getNthMetal().

* New: Hurricane::DataBase::getCell() method to search a cell through
    all the libraries of *all* the frameworks, not just Alliance.
    Also exported in Python interface.
* Bug: In Technology::getNthMetal() the function was not returning the
    right metal, there was an offset of one. And when the offset was
    0, no metal was even returned. Same fix goes for getNthCut().
      The fault was in Mask<>::nthbit().
* Change: In Hurricane::CellWidget, the initial window size is too tiny.
    Increase the size from 250 to 500 pixels.
