Touhouvania Aliases

BUR #44158 is pending approval.

create alias touhouvania_1 -> koumajou_densetsu_1
create alias touhouvania_2 -> koumajou_densetsu_2

Common fan nick name for the games and the series tag has the Touhouvania Alias already.

If the series has an alias tag already, then this additional alias seems unlikely to add any additional utility.
