Reformattd as per CPAN::Changes::Spec

Hi,

Here's a reformatted version of your Changes file. That was a meaty one! :-)

One thing to note: there are 2 released I marked with "not released". This is supported in the latest version of CPAN::Changes::Spec, but that version hasn't been released to the [CPAN Changes Kwalitee site](http://changes.cpanhq.org/). So when you release this it will report as invalid. But then when the site gets updated, you'll flip to passing.

The other way I deal with this is to change such releases to

    [1.21_7 not released]
    * blah blah

Since it wasn't actually released this means that only things left-aligned were released to CPAN. If you're happy with that approach, I'll update this change, but you said you wanted to minimise information loss.

Cheers,
Neil
