[DFDL-WG] bit order documents updated

[Mike Beckerle]

Of course as soon as I post this I get the information needed to resolve
several things.

The new byte-order enum is not needed, so I removed that material. The bit
order document is now a fairly clean thing trying to be an errata.

Please review: draft-gwdi-bit-order-features-v3.0.docx

I created a separate working document on "Mixed Endian Byte Order" should
we ever take this up again.

I also removed the TDML stuff into the TDML document. (now v2).
