Kitsu MAL Rating patch

[kazzarin]

Fixes some remaining issues:

• Certain MAL entries were structured differently which was causing errors
• The rating bar would be recreated each time when going to another media page
• The rating bar would not be inserted if the original was not on the page

Looks good, but testing it out, I found this issue. Happens when switching to a page that doesn't have a kitsu rating bar from a page that has both.

I think it's a timing issue, because it doesn't happen everytime, if the URL changes before the content gets switched out barCheck thinks there's a bar, but there isn't one by the time App.getMalLink completes.

I'll merge it because it's still better than the current live version, but would be good to sort out the timing issues. Sometimes if you go to another page and it swaps out the content too slowly the bar on the current page will get updated, and then removed when it finally swaps out the content.

Sorry about that. I think some recent changes with the way media pages are loaded sped things up making the bug much more apparent since my testing from a couple days ago didn't show anything unusual.

Makes sense, and thanks again for the pulls.
