Releases for Hotspot captive portal

Initial release of the hotspot module. Right now, the login is not integrated with the drupal users database. But, you can use your drupal portal as your CoovaChilli captive portal and the module will provide you with a login prompt to get internet access. There is an setting for 'auto-provision' whereby you can have the module log in users (pre-configured in your RADIUS server) with the general use username and password set. There are also settings for realm and a dialog for "Access Codes" which will authenticate based on an alternate realm (for codes pre-configured in the RADIUS server).
