Subject: [PATCH] Fix live graph never rendering: guard against Infinity
 samples

At the very start of a measurement the elapsed time can be ~0, so the
first speed sample (dTotal/dtTotal) evaluates to Infinity. isNaN(Infinity)
is false, so the sample enters values[] and maxValue stays Infinity for
the whole test: every point of the live graph collapses to y=height
(invisible polygon) and calcPoints produces NaN coordinates (SVG errors
in the console).

Fix: only accept finite samples in Graph(), and guard the perc division
in calcPoints. Applied to both app-2.5.4.js and app-2.5.4.min.js.
