Use consistent bit ordering and variable names

If bit-orderings are to be parsed from left-to-right,
then make the bit-strings left-justified.
If bit-orderings are to be parsed from right-to-left,
then make the bit-strings right-justified.

Section 3.1, which describes how prefix codes work
shows prefix codes that are "left-to-right", which
is better for demonstrating how the work. However,
most of the rest of the document uses a "right-to-left"
convention. We should distinctly say at the end of
section 3.1 that we are switching conventions.

Thus, change the prefix code in section 3.5 to be
"right-to-left" to be consistent with sections 9.1
and 9.2.

Also, change the variable names in section 7.3 to
be consistent with those used in section 10.

Also, change the description of MNIBBLES to be
"MNIBBLES - 4", similar to the convention of saying
"MLEN - 1". Beforehand, the phrase
"If MNIBBLES is 0, then ..." was unclear whether it
meant MNIBBLES before the "plus 4" or after.
