Use github issues instead of Jira

Or at least open the issues here so people can report them here, somebody has proboly written a bot that will open issues reported on github in jira.  If you want users to report bugs they find then using an issue tracker that requires making an account is going to be a hindrance. Using an issue tracker that doesn't allow registration

that says we don't care about our users.
