New features and feedback (Working example attached for 5.2)

Hi!

I have used this module with 4.6 and have modded it somewhat to meet out company's needs. I am really glad that development has started again and I decided to upgrade our intranet to 5.2. I downloaded the latest development snapshot (attached) and integrated it with the site I have also ported my mods to it (attached). The following features have been added:
1. Works with Drupal 5.2
2. Alternative compact list view (hardcoded)
3. Printer friendly page (of compact list view)
4. Download VCards
5. Added callto: links (requires one line update to filter module to support "callto:" protocol)
6. Added moderator function for updates.
7. Support for custom fields using mozillaOrgPerson: Skype and Privat mobile (hardcoded)

The features are specifically adapted to our company's needs but my hope is that they are still generic enough for most people's uses. The code may not be the prettiest or follow Drupal best-practice, but unfortunately I do not have more time to polish my changes.

1. Uploading pictures does not work, although I have not tested that so much since we have been using phpLDAPAdmin.
2. I have added a "$user->uid" check that need to be verified.
3. The "Search Address Book" link points only to the root page (see screenshot). I don't know how to fix that.
4. There are some hardcoded paths to the images, i.e. "modules/". However, the modules can be placed in a subdirectory, e.g. modules/contrib, which breaks the images paths.
5. There are some bug fixes made, which you can see from a diff of the attached files.

Some feedback:

1. It would be better to have a textarea for the "Fields of interest" and "Fields for summaries" since these lists can be very long.
2. In the "todos", the LDIF import/export todo is probably not interesting for end-users. VCard support is more useful since it is recognised by most clients.
3. I am not sure, but can images be included in VCards?

Just let me know if you need more info.
