[EventCalendar] Glitch in ec3.js

[H.Grahl]

With 3.1.1._rc3 I encounter the problem that if the Javascript creates the 
calendar, say by forwarding to the next month, the link to all events from 
the month is formatted like ?year=2007&monthnum=11 while on page load the 
link for the current month is ?m=200712.
Since the JS variant breaks for me I changed line 104 in ec3.js to  
c.href=ec3.home+'/?m='+year_num+month_num;

And now it's working fine for me. I hope this hasn't been mentioned yet but I 
didn't see anything while skimming the archives. The WP install was 2.3.1.
