Add option to select male/female voice for a richer tts experience

Added the ability to choose male/female voices for a richer experience

• Use the implemented UnitSex() method to determine the gender of the unit.
• If the gender cannot be determined, the default voice will be used.
• If the gender can be determined, the appropriate male or female voice will be applied.

Cool, my only issue with this is that you've added English strings to the other locale tables. This is not necessary. enUS is always loaded first, so if no replacement exists then it will just use English.

Ok, As you requested, I have restored the other files to their original state and committed the changes.
