comment_notify 5.x-2.0

This is a new release on a new branch of the code with new functionality. This release is a stepping stone towards the 6.x release which will be coming soon. If you currently use comment_notify you will need to upgrade to the 2.x version of the code prior to upgrading to 6.x-1.0. Once this version has known users who upgraded successfully then I will be able to create and release the 6.x-1.0 version of this module.

This new branch also attempts to provide PostgreSQL compliance. If you were avoiding this module because of a lack of PostgreSQL support, please help test this new version so we can make it compatible with both databases.
