#39 Click on stack trace in interactions and jump to loc

[Brian Stoler]

When an interaction throws an exception, the stack
trace is shown. It would be very helpful to be able to
click on an entry in the stack trace and have DrJava
jump to the offending line (opening the file if necessary).

This could be presented visually by making each stack
trace item look like a link, or it could be done by
putting a small button next to each trace item ("go").

(I actually started trying to implement this a while
back; when I get some time I'll append my discoveries.
Ask me if you want to work on this before I have done so.)
