Display the date and time in a readable format
Don't call instance methods as class methods
Don't display random nothingness if there's no Jira description
I think this is done
Update header style
Add Jira detail in the form of labels to GitHub issues
Close the issue if it was already closed in Jira
Change formatting of labels

Labels are normally lowercase so do that with ones where it will look
sane. Also don't prefix with the type as I think it's unnecessary
Ugh, some issues have no priority (even though I think it's mandatory)
Get comments from the Jira API too

I've switched to using a branch since we might have to push other
changes and I'm not likely to submit the patch required for comment
functionality upstream
Add comments to the issue

Fixes #5
Add a horizontal rule before the comments
Add another new line to properly separate comments
