/**
* Act on user account actions.
*
* This hook allows modules to react when operations are performed on user
* accounts.
*
* @param $op
* What kind of action is being performed. Possible values (in alphabetical order):
* - "after_update": The user object has been updated and changed. Use this if
* (probably along with 'insert') if you want to reuse some information from
* the user object.
* - "categories": A set of user information categories is requested.
* - "delete": The user account is being deleted. The module should remove its
* custom additions to the user object from the database.
* - "form": The user account edit form is about to be displayed. The module
* should present the form elements it wishes to inject into the form.
* - "insert": The user account is being added. The module should save its
* custom additions to the user object into the database and set the saved
* fields to NULL in $edit.
* - "load": The user account is being loaded. The module may respond to this
* - "login": The user just logged in.
* - "logout": The user just logged out.
* and insert additional information into the user object.
* - "register": The user account registration form is about to be displayed.
* The module should present the form elements it wishes to inject into the
* form.
* - "submit": Modify the account before it gets saved.
* - "update": The user account is being changed. The module should save its
* custom additions to the user object into the database and set the saved
* fields to NULL in $edit.
* - "validate": The user account is about to be modified. The module should
* validate its custom additions to the user object, registering errors as
* necessary.
* - "view": The user's account information is being displayed. The module
* should format its custom additions for display and add them to the
* $account->content array.
* @param &$edit
* The array of form values submitted by the user.
* @param &$account
* The user object on which the operation is being performed.
* @param $category
* The active category of user information being edited.
* @return
* This varies depending on the operation.
* - "categories": A linear array of associative arrays. These arrays have
* keys:
* - "name": The internal name of the category.
* - "title": The human-readable, localized name of the category.
* - "weight": An integer specifying the category's sort ordering.
* - "delete": None.
* - "form", "register": A $form array containing the form elements to display.
* - "insert": None.
* - "load": None.
* - "login": None.
* - "logout": None.
* - "submit": None:
* - "update": None.
* - "validate": None.
* - "view": None. For an example see: user_user().
