Changed "convert_spectre.py" to "spectre_to_spice.py".  Corrected the script
to properly identify weird "spectreisms" in which resistors or capacitors
are prefixed as subcircuits with "x" but use a model which is a resistor or
capacitor.  Also:  Added more handling of SRAM (coreid) layers in the magic
techfile for support of OpenRAM, and added a first pass at fill pattern
generation in magic.
