[PHPiCalendar-DEV] code cleanup patch

[David F. <da...@d2...>]

while poking into the event stuff, I found there's a decent amount of 
redundancy, specifically in the $url passing to openevent() - it's in 
the $arr variable, and it's also then seperated out into it's own 
argument (but the function ignores that, and uses the value from $arr if 
it's there) - I went through all the calls to openevent, and cleaned it 
up. Patch attached, decently tested - I didn't actually verify it's 
being correctly passed for every value, but it's a pretty simple patch. 
Against latest cvs, etc. etc.
