Writing parameters into VCD files makes the values available to waveform tools. This can be done easily enough by writing out a $dumpadd section at the beginning of the file that sets the parameter values. We don't need to track the values over change, because by definition they do not change. This changes the typical vcd output as well, so a few of the regression tests need to be adjusted to account for this. Also, while tracking this down, found and fixed the vvp/README.txt documention for the .param/x records.
