Precise's Ubuntu Software Center gains monochrome elements

Just a month left until the final release of Ubuntu 12.04, yet still various minor UI changes are landing in the polished Precise, fixing, enhancing or strengthening various applications.

Ubuntu Software Center's panels have gained a dark-ish border that adds a clear distinction between the displayed items, as well as on recommendations.

The ranking stars are now black-ish with a light middle-part (for unselected stars).

The above change resulted probably as a visual "alignment" with the monochrome toolbar, adding a + towards consistency.
