	 * column name associated with said field.
	 *
	 * Each item can have the following attributes:
	 *
	 * string $type: The type of field this is - valid types are:
	 *   - callback: This is a field which has its own callback mechanism for templating.
	 *   - check:    A simple checkbox.
	 *   - hidden:   This doesn't have any visual aspects but may have some validity.
	 *   - password: A password box.
	 *   - select:   A select box.
	 *   - text:     A string of some description.
	 *
	 * string $label:       The label for this item - default will be $txt[$key] if this isn't set.
	 * string $subtext:     The subtext (Small label) for this item.
	 * int $size:           Optional size for a text area.
	 * array $input_attr:   An array of text strings to be added to the input box for this item.
	 * string $value:       The value of the item. If not set $cur_profile[$key] is assumed.
	 * string $permission:  Permission required for this item (Excluded _any/_own suffix which is applied automatically).
	 * func $input_validate: A runtime function which validates the element before going to the database. It is passed
	 *                       the relevant $_POST element if it exists and should be treated like a reference.
	 *
	 * Return types:
	 *   - true:          Element can be stored.
	 *   - false:         Skip this element.
	 *   - a text string: An error occurred - this is the error message.
	 *
	 * function $preload: A function that is used to load data required for this element to be displayed. Must return
	 *                    true to be displayed at all.
	 *
	 * string $cast_type: If set casts the element to a certain type. Valid types (bool, int, float).
	 * string $save_key:  If the index of this element isn't the database column name it can be overridden with this string.
	 * bool $is_dummy:    If set then nothing is acted upon for this element.
	 * bool $enabled:     A test to determine whether this is even available - if not is unset.
	 * string $link_with: Key which links this field to an overall set.
	 *
	 * string $js_submit: javascript to add inside the function checkProfileSubmit() in the template
	 * string $js:        javascript to add to the page in general
	 * string $js_load:   filename of js to be loaded with loadJavasciptFile
	 *
	 * Note that all elements that have a custom input_validate must ensure they set the value of $cur_profile correct to enable
	 * the changes to be displayed correctly on submit of the form.
