Update documentation to talk about lower case vs. upper case for the sql string

Using latest Feeds and Feeds SQL Module as well as Drupal-7.14.

Everything was working well until I upgraded from 7.12 to 7.14 recently, now feeds no longer imports on cron, and when I do a manual import, it looks to import the correct number of items, but the nodes that are created are blank.

The only obvious error I'm seeing is

Notice: Undefined index: FeedsSQLParser in FeedsSource->getConfigFor() (line 584 of /var/aegir/platforms/mrcintranet/sites/all/modules/feeds/includes/FeedsSource.inc).
Notice: Array to string conversion in FeedsFetcherResult->sanitizeRaw() (line 70 of /var/aegir/platforms/mrcintranet/sites/all/modules/feeds/plugins/FeedsFetcher.inc).

Have tried attaching to a content type, and using a standalone form. When setting the query in the SQL parser, it is able to pull back a sample, so I'm guessing that it's unlikely to be any kind of connection problems. I've tried deleting and redoing the importer. Uninstalling Feeds/FeedsSQL completely and even updating to the latest dev release.

Sample Feeds config is as follows:

$feeds_importer = new stdClass();
$feeds_importer->disabled = FALSE; /* Edit this to true to make a default feeds_importer disabled initially */
$feeds_importer->api_version = 1;
$feeds_importer->id = 'antibodies';
$feeds_importer->config = array(

Anyone got any ideas where I'm going wrong? I'm not sure whether it's a Feeds problem or a Feeds_SQL problem but thought I'd try here first.
