Change "Installed" to "Active" in admin/modules view.
Fix formatting in admin/modules_confirm view.
Minor revisions to Admin_Modules controller.
- change $info to $module_info for consistency with admin/modules view.
- remove redundant active module checks ($info->active and
Module::is_active($module_name) do the same thing...).
Big rewrite of Admin_Modules controller.
- use Formo to build form as object.
- change modules and modules_confirm views to render the Formo form elements.
- squash 3 actions and 1 helper function into one, linear action.
- remove redundant CSRF checks (Formo already does this)
Fix/note some oddities in Module class.
- fix Module::upgrade() so it works on non-activated modules.
- add notes indicating that set_version(), not install(), creates DB entries.
- revert removing load_modules() from install(), which is needed to refresh
Module::$active and Module::$modules.
- add note to upgrade() re: load_modules(), just like install().
Add Theme::$kohana_themes variable to store theme paths.
- use in Module::load_modules() so, when we update paths, we don't lose the themes.
- remove the @todo note in Admin_Modules - the redirect is no longer needed.
Change "self::" --> "Theme::" in Theme class.
Revise Formo overload to set the checkbox template as the std field template.
Make our Formo form/group templates better - they now preserve order better.
Convert Admin_Movies to Formo.
