[X] Issue when applying Actions|Case conversion to tags in greek (the letter Σ should become ς when at the end of a word)

Regarding "case conversion" ... Mp3tag yet does not take into account linguistic specialities, ...
it just changes the lowercase of each letter by letter.

We have already discussed this problem of the end-form of letters in greek language some time ago, somewhere buried here in the forum.
