Remove six languages from Blender UI (rational: very low level of translation, 1-2% at most, and no commit done in branch since more than one year): fi (Finnish), ca (Catalan), bg (Bulgarian), el (Greek), ne (Nepali) and pl (Polish).

Also fix compile in paranoid warning=errors mode for own last commit.
