This is a major change that I have been testing and writing locally. I just tagged UNSTABLE4 before this commit so there's a point to go back to if I end up having to roll back.

* Add per-location-field weights and defaults.
* Add location_api_variant() that I will increment when breaking something in the future that might be used from another module. It is now 1.
* Make settings on location_cck work nicely.
* Field settings are now in a table.
* Field settings defaults can now be overridden in the UI.
* Field settings are now weighted. (Draggable in D6!)
* "Force Default" may now be used for all fields.
* Content type settings validation is repaired again.
* Major COW changes (again) -- Should not have any impact on sites, but be careful until the new code is proven.
* Tests were added to ensure COW functionality doesn't break. (Tests were committed earlier)

API Changes:

* If you were using a location_element, the #location_settings is now the *entire* settings array, not $settings['form']['fields']!
* hook_locationapi() 'collection default' and 'default values' ops  have been merged into a single 'defaults' op, which now allows specifying default weight.
* Collection status 3 is now 4. (Relevant for the 'country' field.)

Should fix the issue brought up in #183004 and #326624.

Tested on MySQL and PostgreSQL.
Please be careful until this code is fully proven!

Split token support into its own include file.
Fix views 2 support for location_fax and location_phone.

Split location_search variables out from the main settings page, as they were confusing *ME*, which means that they were probabaly REALLY confusing the *users*.

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.

Attempt to move the additional stuff into the main array.. This will be followed by an attempt to merge the location and user_location stuff together.

Thanks!

Location generation module for help with development / debugging.

Move location_search theme function into location_search.module.
