Prefix, Suffix and Exclusion Suffix

An optional Prefix, Suffix and Exclusion Suffix can be set for each language.
Using the language-specific Prefix, Suffix and Exclusion Suffix with the Material file name can avoid any confusion in case files with identical names exist in different languages.
The Prefix, Suffix and Exclusion Suffix setting is always applied to all the sound Materials for a language. It cannot be applied to only some of them.
