Add command 'write_ic'

Write out the right hand side status of the matrix in format
.ic = V(node_xx)
This may be possible at the end of a simulation or after a 'stop'
of the simulation, which may be resumed again afterwars. This
status may be used to start another simulation with these
parameters by inluding into the netlist.
