JS Registry

Similar in spirit to the theme registry, this module allows core and module javascript files to be overridden by being placed in an alternate location.

The logic is as follows:
1. A module can override a javascript file from drupal's core "misc" folder by placing a file of the same name in the module's "misc" folder. If a module is taking advantage of this, it should list the jsregistry module as one of its dependencies.
2. Files in "sites/<site>/misc" and "sites/all/misc" override files in the module's "misc" and drupal core's "misc" folders.
3. Files in "sites/<site>/misc/module_override/<module_name>" and "sites/all/misc/module_override/<module_name>" override javascript files in a module's folder.

The above is the default logic. This module also invokes hook_js_registry_alter(), so other modules can adjust the registry to something else.

This module depends on the jsalter module.
