Merged requested to merge improve_html_summary into master
Some improvements for the html result page (as suggested in #1 (closed)):
- Changes title to 'Autotester Results' and reduces the padding of the header
- Fixes problem with traffic light colors not visible in chrome
- Adds footer with link to Autotester repo
And also fixes wrong colors of plus/minus sign in chrome (the signs showing the state of the collapsible).
