Relative path in stack traces

[eric]

I see in #101 that it used to be the case that the path along with the filename was included in the UI for stack traces (similar to how ruby is). Now it's only showing the filename unless you mouse-over, which isn't easy to see a full stack trace.

How do I get the path along with the filename to be included? We use go build -trimpath when we build right now so that the full path names don't have meaningless prefixes.

This is indeed an accidental omission, going to fix that. Thanks for reporting, @eric!
