Visual indicator for running application in plasma panel too small

[ivaylo-iliev]

Let me first start by saying this is a great theme and a great work. Thank you.
As for the issue - well I think that the visual indicator in plasma panel that should show the running applications is too small to be easily seen. I did opened the tasks.svg in Inkscape and saw that the height (in case of horizontal panel) and width (in case of vertical one) are only 2px. Playing around and increasing the height/width to 4 actually provided quite good results providing more of the visual indicator to be seen on the panel and allowing the indicator to be actually seen.
