Added support for GF180MCU, part 1. 

* New: In LefImport::LefParser, add support for LEF Polygons that are
    translated into Hurricane Rectilinears.
* Change: In LefImport::setMergeLibrary(), the default behavior for the
    LEF parser is to create a new separate library under LEF/<lib_name>
    for each file. But if the various cells are put each one in it's own
    cell, this is suitable. So we can now set a library beforehand into
    which they will be all put.
* New: in CRL/technos.node180.gf180mcu, configuration files for the
    GF180MCU open PDK.
* New: in cumulus/designflow.technos, added a setupGF180MCU_GF() to
    initialize the GF PDK.
