I cowboy committed rPf311f3f9 to fix a fatal which was preventing me from filing tasks, so here's the followup. :P
Adding images to Conpherence threads could fatal their handles after you added an image to a thread. Here's the trace:
```

```
Specifically, `getDisplayData()` tried to access `$this->getImage()`, but that might not be loaded.
I just refactored things a bit to try to dodge the need to hit the image, since we only need the title. I //think// I got things right, but let me know if I missed something.
I also removed `js_title` since it looked like it was always exactly equivalent to `title`. I figured that must be a leftover from a while ago.
