Trying to correct the glyphs in subreddit manager

It *should* look like that ^, but the glyphs can change significantly depending on your installed fonts. I had to use monospace to remove the [jaggies](https://cloud.githubusercontent.com/assets/7245595/3425711/fdc67b1a-000b-11e4-8d1d-01622967ba5a.png) from the gt/lt signs, but that made the up/down arrows too small and unaligned, so I set only them to verdana (any other font and the alignment goes off).

Below shows the difference the font-family can make, the first one is monospace and the second is using sans-serif. On my system the monospace is smooth, while the sans-serif is pixelated/jagged. In Verdana (reddit default) it looks so much worse.

#### `↑↓<+>` ↑↓<+>

I'm not sure how they compare on OSX and Linux.

This is how it would look in monospace with the left/right sorting arrows:

#### `⇆<+>`

It aligns much better than the up/down arrows.

Thoughts?
