[dev] Moment: attendee availability... still

[Dan Wilson]

Ok... after some further investigation, I decided to check the horde logs (I 
know... novel idea).

And this is what I found:
Feb 27 12:23:06 kamino HORDE[28353]: [kronolith] Permission denied to 
calendar "dwilson at acucore.com" in Kronolith::generateFreeBusy() [on line 28 
of "/xxx/horde/kronolith/fb.php"]

Now, it works just fine when viewing straight to the url, but when going 
through the attendee availability, it doesn't like it.

So... I went in and changed the permissions on my calendars and shazzam!  It 
now works (kinda)... with a couple issues:

1. The code should gracefully handle this situation.  I detemined that the 
Moment::getFreeBusy() function didn't return a PEAR_Error in this case... it 
just returned false.

2. Although I know the information is coming back correctly (through a call to 
var_dump), it doesn't display correctly.  I have a line for each attendee, but 
the entir dislay bar is blank (no colors at all... no even 'No Information').  
It also doesn't show in either the 'All Attendees' and the 'Required 
Attendees'... they both show as 'No Information'.
