Fix issue link in issues page

The link assumes that the issue belongs to the signed in
user, which is not necessarily the case
I changed it to use repository owner name instead

modify the file path

move etc/supervisord.conf to conf/etc/supervisord;
remove tmp folder, then all logs move to log folder;
move the supervisor.pid to /tmp folder.

add supervisor support and script, easy to use.

just like ./gogs_supervisord.sh start
./gogs_supervisord.sh stop
./gogs_supervisord.sh restart
and logs all saved tmp folder
