Doesn't preserve comments

[pbreuer]

Source code conversion should preserve comments.
Also the trace info in the conversion output should have relative not absolute paths, relative to either the top module directory or the current directory at execution. I supplied relative paths to sv2v.

Otherwise output looks good! Layout seems to be preserved as far as is possible.

</ wish list>!

It's needed at least in order to preserve the // verilator lint_off and lint_on directives in comments.
