Reviewed by Timothy Hatcher.

* BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Images/checkmark.svg: Added.
* BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Scripts/StatusLineView.js:
(StatusLineView.prototype.set repeatCount):
* BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Styles/StatusLineView.css:
(.status-line.good .bubble.pictogram):
Use an SVG image instead of an obscure font for the checkboxes so they
render identically on all platforms.
