Releases for MailQ (Mail Queue)

Release notes

This is a rewrite of the 6.x-1.x branch and is incompatible with the 6.x-1.x branch. There is no update path other than to uninstall the 6.x-1.x version and install the 6.x-2.x branch.

The following are some of the changes in the 2.x branch

- Took out mailq_running_batch variable as we are no longer using that
- Replaced truncate query with delete from flush table query
- Corrected the value for the drupal_default library in admin settings form
- Added function mailq_is_mailq_enabled to check if mailq is enabled instead of checking for variables directly
- Moved the drupal_mail_wrapper function to an include file to be included conditionally on mailq being enabled
- Added cleanup of variables on uninstall
- Took out the inclusion of mailq.mail.inc via the module as this will be done by drupal_mail_send itself
- Set the initial mailq_send_library to the current smtp_library in the site
- Restructured the processing of mails in mailq. Took out hook_mail and started storing the message directly as a serialized object. Currently calls drupal_mail_send instead of drupal_mail or drupal_mail_wrapper in cron
- Changed database structures, took out the log table
- Added README with information about how mailq works
- Changed mailq config optionss to textboxes instead of select boxes to give better control for users
