On a small screen the buttons fall out of line

The new buttons that got added in #250 fall out of line when the screen is small.

@supakeen I'm thinking we can add flex to the container and add margin-left: auto to the remove now button.
If that is Okay, I can work on this.

It will look something like this,

@millefalcon of course you can work on this; just to be sure: this happens in multiple places (also on the new paste page).

@supakeen Got it. I'm kinda not sure where exactly we should put the margin-left: auto. I see the "remove" button in the create paste is added using javascript, so should i add the class there, or just put it in the scss ?
Currently, I was planning on adding helper class like ml-auto { margin-left: auto } and just use the class in code.
