Speed & Max flow tuning wrong console command

[ghylander]

In the calibration.html file, line 1199 reads:

<p>You can enter <b>M203</b> into a terminal and the maximum set feedrates will be reported.</p>

However, sending M203 does not echo anything. Later in the same section, in line 1204:

<p>You can enter <b>M503</b> into a terminal and these values will be reported.</p>

Which does indeed work. Seems to me that both lines should state M503.
