Even though the modified border width and padding did cancel each other a full layout recalculation was necessary. This is rather expensive when a lot of entries are loaded. This patch avoids the problem by adding a second div with a border that is invisible by default. If an entry is selected, the border's color is updated. See https://developer.mozilla.org/en-US/docs/Tools/Performance/Scenarios/Animating_CSS_properties#CSS_property_cost for some details on the costs of a CSS property.

These commits improve scroll performance by avoiding some unnecessary layout recalculations. This should help a bit with the performance issues in #148.
