Remove search engine verification, promote separate module

Sounds good.

So what do we need? I was thinking:

1. Note in the Nodewords README.txt file & project page about the change.
2. Add a note to the Site_Verify README.txt and project page about the change.
3. Convert the settings, e.g.:
   • Specifically do NOT remove the settings, leave them as-is. Write an update & import script for Site_Verify that checks to see if the settings were configured for Nodewords and import them if found.
   • Write an update script for Nodewords to convert the settings for use with Site_Verify.

Whaddya think?

Given that Site_Verify has conversion scripts for other modules already, I'm going to write a patch for it to import the Nodewords settings.

Site_Verify issue for the conversion script: #1028246: Import script for Nodewords settings

I've written a patch that converts Nodewords settings, both as an update script and during installation.

Here's a patch that removes the nodewords_verification_tags module and adds a small update script to both remove the now unnecessary variables but also notify users of the change.

I think this should be in the next release.

Small update to the patch that fixes variable_get() calls and removes the record from the {system} table.

Small SQL bug in the last patch.

Rerolled the patch.

Rerolled for 6.x-1.x, lets see if it passes this time.

Committed.
