Some Hokuto no Ken localization

BUR #11622 has been approved by @evazion.

create alias thouzer -> souther
create alias thouther -> souther

In the later Hokuto no Ken media (especially translated version), Souther's name were romanized as "Thouzer" (or less commonly as "Thouther"), and some of the HNK fans have comes to knew him by this name. I think this should be aliased to his original name.

BUR #21082 has been approved by @nonamethanks.

create alias juda_(hokuto_no_ken) -> yuda_(hokuto_no_ken)
rename uighur -> uighur_(hokuto_no_ken)
rename ryuuken -> ryuken_(hokuto_no_ken)
rename kouryuu_(hokuto_no_ken) -> koryu_(hokuto_no_ken)
rename kaiou_(hokuto_no_ken) -> kaioh_(hokuto_no_ken)
rename ryuga -> ryuga_(hokuto_no_ken)

Some other qualifier-less HnK tags and official romanization. Added "Juda" alias for Yuda as his name were occasionally localized as this, and add qualifier to Uighur to disambiguate him from the actual ethnic group.
