Add behavioral (LOGICEXP, PINDLY) test for 283 circuit. There are glitches in the simulation for some of the s* outputs. Probably due to not having inertial delays. And why not set 'zero' delays as close to zero as permitted by XSPICE.

Fix bug #602 "Warning message trying to linearize a transient analysis vector"
by changing the way "ngspice -a" (autorun option) works. The inserted code
now checks whether a simulation has already run by examining $curplot
before forcing "run". Also at most one simulation is forced to run.

.probe alli improved:
* Enable current mesurement for I source
* Look at only the first 2 nodes of S and W switches
and F and G controlled current sources, measure current
with = voltage source added to second node. So we get
I(Fx), I(Gx), I(Sx), and I(Wx).
