[EventCalendar] Get events by tags

[Benedikt Roth]

Hi all!

I'm using EventCalendar 3.1.1.rc3 and really like it. Good job.
However there is one feature I'm missing: I would like posts with  
attached events to show up when browsing the archives by tags.
For example the url "/tag/concert/" should display all posts about  
concerts, including those with events.

Especially it's a bit confusing having a tag cloud on the page but  
some tags give a 404 because the only post belonging to this tag is a  
event post and thus hidden.

Is there a way to achieve this?

Cheers,

	Benedikt
