ZMSCalendar v2 - bugfix

Dear zms devels,


i've found a bug in ZMSCalendar during this december.

If the calendar shows more then one month and is in a december currently the 
calendar overview shows:
	dec 2009
	jan 2010
	jan 2010
	jan 2010
	...

If i go forward one month by calendar arrows i get the correct output as 
usual:
	jan 10
	feb 10
	mar 10
	...

so i've searched around in the special object "Calendar" and found in 
"displayCalendar":	

<dtml-if expr="REQUEST.get('im')>12">
 <dtml-call "REQUEST.set('iy',iy+1)">
 <dtml-call "REQUEST.set('im',1)">
</dtml-if>


by changing this to:
<dtml-if expr="REQUEST.get('im')>12">
 <dtml-call "REQUEST.set('iy',iy+1)">
 <dtml-call "REQUEST.set('im',im%12)">
</dtml-if>

it seems to work for me now.

But i'm not fully understanding the ZMS Calendar object. It would be nice if 
someone could validate this (or even has a better solution here ;).

many thanks.

best regards,



Niels.
