-----------
BGE PyAPI
while making a demo of using python to control bones found some more problems.
also added channelNames attribute to BL_ActionActuator to get a list of valid channels to use.
demo: http://www.graphicall.org/ftp/ideasman42/armature_python.blend
its still not that useful since theres not way to know rest bone locations yet but better then nothing.
