Preliminary / experimental vCalendar support

(Not a feature request, I'm actualy proposing + providing the feature ;-)

Hi, I've been working with Drupal for a while as a site-builder / web-hosting provider but I'm just starting to get my hands dirty as a developer/contributor.

I've written a patch that adds vCalendar support to event.module. This patch is preliminary and experimental (think "alpha release") but I'll be working on it over the next week or so.

You can read about it at http://drupal.org/node/7255. I'm also attaching the patch directly here, and you can read more (and download the current and future rev's of the patch) at http://danyell.com/patches/event/vcal

I'm posting this now (even though it may seem a bit premature) because I'd like to coordinate my efforts with anyone working along similar lines, so as to invent only one wheel.

TODO. My next planned steps are:

- Apply all other available patches ot event.module (my patch was made against the original 4.5.0 release) and amend the vCalendar feature accordingly (e.g., to support event end-dates);

- Fix or find a workaround for an annoying bug in the currrent vCalendar feature wherein IE 6.0 SP2 under WinXP SP2 fails to properly hand off the vCalendar object to Outlook 2002 when both are running (works great, ironically, with FireFox 1.0 and Outlook 2000+);

- Add iCalendar support;

- Do some more QA on: Mozilla and FireFox on Linux (9.0 and Fedora FC2), IE 5 and Safari on Mac (OSX). I have a full QA setup here with Windows, Linux, and MacOS boxes and all the major browsers installed on each.

Sorry to be so long-winded for such a minor feature. Please post here or drop me a line at http://danyell.com/contact if you're working on this or related features; to send additional requests / requirements for this feature; and above all to let me know if the patch did or didn't work for you (please include version info of everything: your Drupal + PHP + webserver versions, Your OS + browser, etc.)
