Add a correction to the previous change of inppas4.c, which freed devname and left instance name pointers in DEVnameHash pointing at freed memory. This commit adds the devname string to the symbol tables which are eventually cleared by INPtabEnd. Also, if a capacitor in the spice netlist has the same name (unlikely, but possible) as a shunt capacitor, then no shunt is created, and a warning is issued.
