Tather than encoding the checked status on the bug, this should be 
```
"checked" if bug.status == "notstarted" else ""
```

I'll also need to check the output to make sure that it ends up as proper HTML <input checked> and <input> rather than checked="" or checked="checked" which isn't totally browser-compatible.
