Fix gitignore for results directory
Allow putting result sets into in-page tabs (Ben Bleything)

not producing a useful graph, so that change is adopted in all graphs.
Fix URLs to individual test results.
Existing code required server directory browsing.
Updated version uses direct addresses, which work locally, too
