Releases for Registration Secret Codes

Initial 7.x-1.x version. May or may not actually be working at any given point.

Second stable release for the 6.x-2.x branch of the code with code style cleanup and a slight security improvement (filtering admin-entered text to prevent a site admin from executing a cross-site-scripting attack).

Seems to basically work :)

This is a rewrite of the module as compared to 6.x-1.x, focused on a single secret shared registration code. This is handy for sites that need to have public registration enabled, but where the registrants are a known group (e.g. people who attend a physical event together) where it is easy to share information like a secret registration code.

Applied coding standards. Some nonstandard code left untouched for performance reasons (it's minor and poses no security issues).

This nightly snapshot involves some general cleanup, following Drupal's coding standards. Very few things are left nonstandard, but for good reasons.
