Toggle weeknumber in calendar applet

[VeederLicht]

Hey people,

First let me stress i am excited to see this new DE pickup steam, i like it already.

I have a feature request: add the ability to toggle weeknumbers in the calendar applet. Here in Europe we use that quite often so it would be great to not have to open a browser and look for it every time.

Thanks.
