Initial port to Drupal 7.
This probably has lots of issues to be ironed out, and really, really shouldn't be used in production.
Changes since DRUPAL-7-0-BETA3:
Rolling development release of the 7.x series of the OpenLayers module
Fixing error in tagging.
Continued development on Drupal 7 branch.
Initial split from CCK for Drupal 7.
See http://drupal.org/node/533222 for details.
Do NOT use this branch: use 7.x-2.x instead.
