UtBS: Fix indirect terrain aliasing: Mm -> Mt
UtBS S8: Add wmllint: recognize directives for units created in later event
UtBS: Add wmllint: recognize directives for dwarf/troll allies in S8 onwards

wmllint doesn't know what $ally_name means in the context of the
prestart [recall], so it complains about references to Grog/Nog and
Rogrimir/Jarl in these scenarios as a result. Since at this time wmllint
can only be taught to recognize character macros, use the "recognize"
command instead.
