Subject: Use popup widget and theme colors for ram-widget.

ram-widget now uses an awful.popup widget. This gives a more
consistent appearance with the other widget and displays the popup
next to the wibar widget, instead of always top right.

Instead of fixed colors, I selected appropriate symbolic colors from
beautiful themes. Therefore, the widget now reacts to
theming. Naturally, The selection of colors are a matter of taste.

Fixes #201.
