Feature Request: use Japanese name for actor role

[org0ne]

I have used this on most of my .nfo exports and realized that this is not something that Javinizer currently supports.

Using the Japanese name as role presents the Japanese characters in an easy to access location which helps immensely if a user wants to do some deeper searching on an actress.

Added setting sort.metadata.nfo.altnamerole to add the actress <altname> as the actress role.

Also changed the <altname> field to be dynamic based on the selected actress language via sort.metadata.nfo.actresslanguageja.

If sort.metadata.nfo.actresslanguageja: 1, altname will be written as the English name.
If sort.metadata.nfo.actresslanguageja: 0, altname will be written as the Japanese name.
