node_style 7.x-1.0-alpha1

Alpha of the D7 upgrade release. There have been a number of changes necessitated by changes to the Drupal theming system and a bunch of new features as well :) They include:

1. The head_title template variable is now a part of html.tpl.php.
2. Support for the "hiding" of regions has currently been nuked as D7 regions are too variable. This and other variable changes might hinder some upgrades. These issues will need to be manually worked out.
3. A new machine name option has been introduced for each style scheme which will be used with the new node_style hooks.
4. In lieu of the hodgepodge of display settings relating to variable page elements, the module now provides two hooks namely hook_node_style_preprocess_SCHEME_MACHINE_NAME() and hook_node_style_process_SCHEME_MACHINE_NAME() respectively. They are simple extensions of the Theme API's hook_preprocess() and hook_process() and can be used to manipulate theme variables whenever a node_style is triggered.
5. The module now optionally injects node file attachments into the page markup. The module supports CSS and JS attachments. The latter is a potential security risk and requires a Drupal variable - allow_insecure_uploads - to be set to 1 in order to work.
6. Node styles can now be associated with node types and will be chosen as the default node style scheme in the node form.
7. A settings tab has been introduced.
8. There have also been some minor UI improvements.
