Removed old styles from when we still had the buttons.

The styles were getting confliceted with each other and
causing the distance button to turn white.
Auto show the distance when calculating distance.

Before, you had to hover over the line that it drew
before it showed you the distance, but now it'll do
that automatically. And if you decided you want to
X out the popup and then you want to see it again
later, then you can hover over it.
