  The icalvcal_convert routine calls icalvcal_traverse_objects to do
  its work.s his routine steps through through all of the properties
  and components of a VObject. For each name of a property or a
  component, icalvcal_traverse_objects looks up the name in
  conversion_table[]. This table indicates wether the name is of a
  component or a property, lists a routine to handle conversion, and
  has extra data for the conversion.

  The conversion routine will create new iCal components or properties
  and add them to the iCal component structure. 

  The most common conversion routine is dc_prop. This routine converts
  properties for which the text representation of the vCal component
  is identical the iCal representation.

/* vCalendar has 4 properties for alarms: AALARM, DALARM, MALARM, PALARM
   (for audio, display, mail, and procedure alarms).

   AALARM has Run Time, Snooze Time, Repeat Count, Audio Content.
	It may also have a TYPE parameter specifying the MIME type, e.g.
      AALARM;TYPE=WAVE;VALUE=URL:19960415T235959; ; ; file:///mmedia/taps.wav
      AALARM;TYPE=WAVE;VALUE=CONTENT-ID:19960903T060000;PT15M;4;<jsmith.part2.=
	960901T083000.xyzMail@host1.com>

   DALARM has Run Time, Snooze Time, Repeat Count, Display String.
      DALARM:19960415T235000;PT5M;2;Your Taxes Are Due !!!

   MALARM has Run Time, Snooze Time, Repeat Count, Email Address, Note.
      MALARM:19960416T000000;PT1H;24;IRS@us.gov;The Check Is In The Mail!

   PALARM has Run Time, Snooze Time, Repeat Count, Procedure Name.
      PALARM;VALUE=URL:19960415T235000;PT5M;2;file:///myapps/shockme.exe

   AALARM and PALARM: Check the VALUE is a URL. We won't support CONTENT-ID.


   iCalendar uses one component, VALARM, for all of these, and uses an ACTION
   property of "AUDIO", "DISPLAY", "EMAIL" or "PROCEDURE".

   The Run Time value can be copied into the iCalendar TRIGGER property,
   except it must be UTC in iCalendar. If it is floating, we'll convert to
   UTC using the current Unix timezone.

   The Snooze Time becomes DURATION, and the Repeat Count becomes REPEAT.

   For AALARM, the Audio Content becomes the ATTACH property, and the TYPE
   becomes a FMTTYPE of this property (PCM -> 'audio/basic' (?),
   WAVE -> 'audio/x-wav', AIFF -> 'audio/x-aiff'), e.g.
     ATTACH;FMTTYPE=audio/basic:ftp://host.com/pub/sounds/bell-01.aud

   For DALARM, Display String becomes the DESCRIPTION property.

   For MALARM, Email Address becomes an ATTENDEE property, e.g.
     ATTENDEE:MAILTO:john_doe@host.com

   For PALARM, the Procedure Name becomes an ATTACH property, like AALARM, e.g.
     ATTACH;FMTTYPE=application/binary:ftp://host.com/novo-procs/felizano.exe

	This is awkward to do as we need to access the DTSTART property, which
