RES 4.2.0 Button changes

I've made the new "big editor" button located next to "formatting help", that's added by RES 4.2.0 look like "formatting help" button, otherwise it was really not fitting in with the rest of the theme.

Also RES added button on top right corner to sort subreddit shortcuts, and it was using gray background which didn't fit in with the rest of the bluish header/shortucts bar. I've made it transparent.

I'm pretty much beginner as far as CSS goes so maybe my code isn't best, but it works. And I wanted to help :)
