Upgrade to Drupal 6

Issue Summary

Hi Lior,
Here is the patch for Drupal 6 I promised. I've added support for Views 2. Here's how to get set up quickly:

- Create a new node type with two CCK number fields. One for latitude and one for longitude
- Create a few dummy nodes of this type
- Create a view and add fields for title, latitude, and longitude
- Select 'Mapstraction' as the style.
- Configure the style by select a API and specifiy the field usage for title, latitude, and longitude.

The view is able to get the lat/lon for each point from either a pair of CCK number fields or the fields that location module provides.

So far, there is support for Google, Yahoo, Microsoft, OpenLayers, FreeEarth, and CloudMade (extends OpenLayers). I plan to add the rest of the APIs once a Drupal 6 branch is set up.

Let me know if you have any questions or problems setting this up!

Cheers,
Will
