javascript lib (gallery.reload.js) which defines the functions
gallery_reload() and gallery_location(new_location). They just
do a window.location.reload() and window.location = new_location.
This change breaks the assumption that all themes will handle page reloads
the same and allows the theme to customize the page refresh.
This required putting a wrapper view around the forms and passing
this view as the parameter to the item_edit_form event. The view
contains a $script variable that the modules can add script to be
included in the form html when rendered as part of the ajax response.
communicate. Almost all controllers now use JSON to speak to the
theme when we're dealing with form processing. This means tht we only
send the form back and forth, but we use a JSON protocol to tell the
browser success/error status as well as the location of any newly
created resources, or where the browser should redirect the user.
Lots of small changes:
1) Admin -> Edit Profile is gone. Instead I fixed the "Modify Profile" link
in the top right corner to be a modal dialog
2) We use json_encode everywhere. No more Atom/XML for now. We can bring those
back later, though. For now there's a lot of code duplication but that'll be
easy to clean up.
3) REST_Controller is no longer abstract. All methods its subclasses should create
throw exceptions, which means that subclasses don't have to implement stubs for
those methods.
4) New pattern: helper method get_add_form calls take an Item_Model,
not an id since we have to load the Item_Model in the controller
anyway to check permissions.
5) User/Groups REST resources are separate from User/Group in the site
admin. They do different things, we should avoid confusing overlap.
