This adds support for having up to 28 distinct sub-achievements within a single achievement. This limit exists since wesnoth's layout isn't smart enough to tell a horizontal listbox to actually use its scrollbar instead of forcing a horizontal scrollbar on the whole window. Additionally this adds the [set_sub_achievement] and [has_sub_achievement] WML tags and their respective lua functions. [has_sub_achievement] is unsafe for use in MP, for the same reasons that [has_achievement] is.
