Script Summary: Add navigation to the comment thread in Bugzilla (J/K/N/L/P keystrokes).
When viewing a bug thread on any Bugzilla installation, you now get keyboard shortcuts:
- J: Next comment
- K: Prev comment
- N: Next bug in list
- P: Prev bug in list
- L: Back to last search
Update 0.2: Added process_bug.cgi to include list so script works when modifying bugs too.
Update 0.3: Don't fire if modifier keys are held down (ctrl/alt)
