Add page: "reference documentation of the label system" about epubcheck-website

[gregoriopellegrino]

What do you think if I get the label list through GitHub's API?

https://developer.github.com/v3/issues/labels/#list-all-labels-for-this-repository

I don't know if the vision is to have any additional info on that page but even in that case, it seems like a great way to start :)

[gregoriopellegrino]

Sure, we need to add a broader description to GitHub's basic information, but at least we're aligned with the available labels (and the site stays updated in the next versions) :)

One question: I'd like to put, next to the label name, the colored square like GitHub:

What does it look like? Do you have any idea how you prefer to do it?

Do I use a with relative CSS, or do we use Font Awsome (https://fontawesome.com/icons/square?style=solid) or similar?

[marisademeglio]

I would use CSS ::before and also template the <style> block to include the right colors for that page. Let me know if I can do anything here to help!

Working on this issue I thought it might be useful to insert a flowchart to indicate the steps between the different statuses of the issues, what do you think?

[marisademeglio]

Sure, do you have some ideas for what that flowchart would look like?

@rdeltour: maybe using a JS library
