Summary: I added a new widget and made some Bug fixes

It was very hard making this processes widget, because there so many processes on a system. If I render every process in the List at once and this on every refresh, it wouldn’t run smoothly. So I render only about 100 at once. I had the same issue with reading the PID list, I solved this using a Cache updating every 2.5 seconds, in an extra Thread.

I also added a Menu to select wich widgets you want so see. And adjusting the Intervall of updates.
