location 5.x-3.0-rc1

Location3 is now supported on Drupal 5, and Location 1.x/2.x are no longer supported.

Changes since DRUPAL-5--3-0-test3:

• Take advantage of the new gmap_get_key function for the google geocoder.
• Move the geocoding options form to location.admin.inc to match the Drupal 6 version.
• Backport commit 131997: Rip out the notion of "supported countries." With the dynamic country loading, this isn't really needed.
  This breaks some of the "province listing" stuff, but it needed work anyway.
• Move location_province_select_options to location_views and modify it a bit. It still has caching issues.
• Sync theming with Drupal 6 version.
• Remove the rest of location.theme.
• Add type synchronization in location_addanother.module.
• #313236 by pounard: Fix emptiness check for view op of hook_user().
• Fix #314835, reported by marcoBauli: Make collapsibility work again. I had accidentally broken this while fixing notices. Additionally, collapsible now works on single-location forms.
• Fix copy-paste bug in location_fax.
• Fix how defaults are used when expanding location elements. This eliminates warnings after enabling location_phone / location_fax, and lets 'collection default' work as intended.
• Extend token support to use all location fields and simplify the code.
  Split token support into its own include file.
• #286159 by Cobalt747@drupaler.ru, location side. Add missing t()s.
• #315705, reported by mburak: Be nice to the Drupal 5 themers and check for overridden templates, instead of making them do a full template.php override.
• Repair broken update that failed to change the weight of location_fax and location_phone. (Preemptive backport of uncommitted Drupal 6 changes.)
• #317048, reported by carlogen: Repair some completely broken views 1 code, namely the province and country exposed filters.
• A bunch of E_ALL stuff and code cleanup.
