HTML reporter for locally displaying report

[mzfr]

We all know that our current displaying method is really not great and we need some clean way of displaying our report.
The current best option seems to have HTML reporter we can use jinja for having a nice format of the HTML page.

PROBLEM

• No records of the previous reports: Sometime we might want to see the difference of the output on two different add-ons/repositories so there wouldn't be any record of the previous run since the reporter will not append but will write to HTML file.

As long as it's only for locally I'm fine with that. But markdown would probably be easier to do.
