				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 subfix which is applied automatically).
				function $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 occured - 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 overriden
								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.

		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.
