Support "KeepAChangelog" format for changelogs

[davorg]

I use the change log format recommended by KeepAChangelog. And MetaCPAN doesn't understand that format. So my changelog end up looking like this.

I know there's a specification for CPAN changelogs but I think it's also good to support other widely-used specs.

I realise this will probably only benefit me, so I'm perfectly willing to put in the work myself. I'm assuming the work will break down into:

• Write a parser that parses the KeepAChangelog format and returns the same data as CPAN::Changes
• Work out how to insert that processing into the changelog display code for the relevant files
• Profit

I'll probably start looking at this in the middle of next week.

Is this going to be in a Changes.mkd or Changes.md, or are you planning on doing a big old $content =~ /\QThe format is based on [Keep a Changelog]/?

Looking through my CPAN modules, it seems I vary between Changes.md and ChangeLog.md. But, yes, that just tells you it's in Markdown - it doesn't confirm it uses the KeepAChangelog format. That certainly needs more thought.
