[X4U] Update Numbering

[Craig A. Finseth]

   This is nit picking but is anyone else bothered by the update numbering
   system? The sequence went 10.4.1 to 10.4.9 then now 10.4.10

   But mathematically 10.4.1 and 10.4.10 are the same amount. They have the
   same value. The zero is redundant. But they are different updates. Can=B9t

In the math that I learned, you can have only one decimal point in a
number.

Clearly, version numbers are meant to be strings and not mathematical
numbers.

(This reminds me of a problem that we had years ago with Novell IPX
network numbers, which are normally written in hex.  Some places
treated numbers that looked like integers as decimal.  Our fix was to
ensure that we ensured that at least one character in the "a-f" range
was in each assigned number.)
