Mass edit: fire_emblem_fuuin_no_tsurugi -> fire_emblem:_fuuin_no_tsurugi

Fire Emblem Fuuin no Tsurugi -> Fire Emblem: Fuuin no Tsurugi

Rationale: Lack of consistency, all other Fire Emblem copyright tags contain a colon. The consistent tag, fire emblem: fuuin no tsurugi, is already aliased to fe6 like the other Fire Emblem copyright tags.

Also if this goes through, fire emblem: fuuin no tsurugi should have the alias fire_emblem_sword_of_seals instead of fire emblem fuuin no tsurugi having it.

Removed existing alias, added:
create alias fire_emblem_fuuin_no_tsurugi -> fire_emblem:_fuuin_no_tsurugi
create alias fire_emblem_sword_of_seals -> fire_emblem:_fuuin_no_tsurugi
