I've moved on to one of the last phases of my work! Now I'm just checking off
items from my last to-do list. The biggest change in this commit is that I made
the moderation reports panel sortable via get request. I also added in page nu-
mbers so that more than 10 reports can be viewed. I'm hoping to go from here to
make a search page. Aside from that, there were only a few other changes I made
this time. I fixed two bugs in my code. I copy-ed and pasted function
mediagoblin.user_pages.views:media_preview_comment which I must've deleted ear-
-lier in a merge. And I moved some of the javascript I was using in the modera-
-tion templates into it's own seperate .js file.
