[EventCalendar] Styling problem on archive pages

[John Yeates]

Slight niggle with the archive pages in 3.1._pre15 and earlier — the  
event date is showing as plain text in square brackets, rather than  
the nicely-formatted red box that comes up on other pages.

As an example, see http://www.westernsussexcamra.org.uk/? 
m=20061017&cat=2 versus http://www.westernsussexcamra.org.uk/archives/ 
134_social-stags-head-cricketers-westbourne/

Not sure if this is by design or not. I removed the parameters from  
the call to ec3_get_schedule() in line 495 of eventcalendar3.php (in  
ec3_get_the_excerpt) which has done the trick. It doesn't *seem* to  
break anything, but two minutes of fiddling does not constitute a  
rigorous test programme :)
