Verona spec: Trailing zeros

[Iris Clark]

Hi.

The JEP is inconsistent with regard to trailing zeros in the version number.  I've made the following modifications:

  - The definition of the version number is modified to remove trailing zeros.  

  - The paragraph defining the short version string `$SVSTR`, in the "Version string" section was split.  The examples of trailing zero elimination were moved to the earlier "Version number" section.  The definition of the short version string remains in the original location.

  - Examples were adjusted to remove trailing zeros as necessary.

I've appended complete diffs.

As always, please let me know if there are any concersn.

Regards,
iris
