Made 'Commits over last 2 weeks' real-time for multi repo dashboard.
Made 'Commits over last 2 weeks' real-time for multi repo dashboard.

Didn't make the whole dashboard real-time because,
it was not possible to make 'Commits over
all time' real-time. 

I will make an issue on github, for making the whole
dashboard real-time.
