[PATCH] Small patch that installs Luisa's two new icons in the tool box.

[Willem Ferguson]

     Install Luisa's Heart Rate icon and her DC-reported ceiling icon

     1) Replace the current text-based heart rate icon with Luisa's design
     2) Move the heart rate graph icon up in the toolbox into the cluster of
        buttons that controls graphs.
     3) Replace the DC-reported ceiling icon with Luisa's latest icon that
        has instrument hands on the face.

Kind regards,
willemf
