* Fixed a bug when protected node is previewed and password is changed during preview
* Refactored hook_nodeapi implementation to use the API functions

* Brought up to coding requirements (hat tip to coder module)
* Changed the global $protected_node_salt to $_protected_node_salt
* Added hook_requirements for more slick user experience
* Removed the node type selector requirement from admin menu [duplicates functionality of Access Control]

- LICENCE.txt has been removed
- .cvsignore has been removed

Also would like to give credit to Gerd Riesselmann (http://www.gerd-riesselmann.net) for his excellent JavaScript password quality and progressbar implementation.
