edits on various web pages about ngtrans and 6bone relationship

[Bob Fink]

I've cleaned up various places on our web pages about the 6bone and its
relationship to ngtrans.

Please take a look (especially Jim :-) and let me know what I've missed.

Note that the ngtrans charter is being changed to the one shown on the
6bone pages about ngtrans:

Thanks,
