Corrected an error in verilog/gl/chip_io_alt.v, which was missing connections to the core side VCCD1 and VSSD1 on the clamped3 pads. Also added scripts for running LVS on chip_io to the mag/ directory, and revised the scripts so that they will only re-run extraction if there is no netlist file in the mag/ directory.

#!/bin/bash
#
Corrected a statement in the LVS scripts in the mag/ directory that is Makefile syntax, not bash syntax, and will cause the script to produce an incorrect LVS result without generating a syntax error.

echo ${PDK_ROOT:=/usr/share/pdk} > /dev/null
Revised the LVS run scripts to use $PDK_ROOT instead of a hard- coded path.

Changed the user project wrapper and user analog project wrapper to be abstract views, and modified the LVS scripts accordingly (they no longer need a special version of the netgen setup script). LVS was verified on both caravel and caravan using this setup.
