Custom sort func for SecureHeaders

[Zeksie]

Would be useful to have ability to set a custom sorting function for the party and raid headers. Useful for named lists, or abitrary class selections that would benefit from class order for example.

So, in the configureChildren function in SecureTemplates.lua, something like this:

	local sortMethod = self:GetAttribute("sortMethod") or "INDEX"; --sort by ID by default
	local sortDir = self:GetAttribute("sortDir") or "ASC"; --sort ascending by default
        local customSort = self:GetAttribute("sortFunc")

        if (type(customSort) == "function") then
                table.sort(sortingTable, customSort)
        elseif ( sortMethod == "NAME" ) then
		table.sort(sortingTable);
	end

That one will never happen, because you could write a custom sort function that sorts raid units by health deficit, which is exactly what they want to expressly prohibit. The best you might get would be a selection of pre-defined (static) sort orders. By class, by level, by group, that's about all you could come up with.

Remember it's perfectly OK to re-arrange unit frames out of combat. So, you can create whatever kind of fancy sorting technique you want and perform the sort before combat starts - it just won't work when in combat. With the right coding, you can even set up a finite set of such sorts and then switch between them with a button press or keybind once combat begins... but again they all would need to be set up while out of combat. Pays to be prepared I guess.
