Various fixes

- Removed unused css from ad units that were removed with pr #224
- Fixed users being able to expand comment reply form horizontally (I am pretty sure. Will have to see how autosize.js reacts)
- Added a css transition for when comment reply form expands
- Fixed a css bug with the "okay got it" button on blotter causing issues in mobile view
- Changed padding on blotter so it is not so large and is more in line with navbar (It's still slightly larger, but its more balanced)
- Fixed an issue with ember logic nesting in favorite-anime-container.hbs (from the emblem to hbs conversion) causing the message for when a user has no favorites from showing up (see original template [here](https://github.com/hummingbird-me/hummingbird/commit/070a623349aae1ae02dcb78d1c2c5b5ddc6099b4#diff-0d77fb82b3ab9f3ed3746bb8732c5f75))
