Bone Names are not exported

Hey there,

I'm one of 0 A.D.'s devs I might have met some of you in Lyon this year, and I have an issue with the script. I'm using a script I made there to generate game specific skeletons for my game, and when using the default exporter it works fine, but when doing so with yours it messes up every name by generic ones is it something I'm doing wrong ? (Since it messes up names I can't use it for the game)
