Add code in ivars.c to look for a SPICE_ROOT environment variable
that gives the location of the ngspice installation. That allows
binaries to be installed in a different directory to the one
compiled in. The spinit startup file is made location-independent
by passing a variable giving the location of loadable modules,
so this fixes Bug #615 -
"spinit contains arch dependent paths, but is installed as noarch DATA".

Prevent crashes in udevices.c when malformed U* instances are present. This would happen with incorrectly written U* gates, ff, latches which do not conform to the PSpice specs. Instead, ERROR messages are output which, hopefully, will help a user to debug their subckt.

Always propgate any individual scale for a vector that appears
in an expression, resolving conflicts by matching length and warning
only when making an arbitary choice. One effect of this is that it
is now possible to mix analog nodes with offset digital nodes
(an expression like dvalue+6) without a warning and get a correct plot.
