[feature] Change "new editor" button.

[TheDutchMagikarp]

is your feature request related to a problem? please describe.
While creating a paste that contains multiple pasties, the bottom pasty will have a button "Add editor". This does (in my opinion) not accurately describe the functionality of the button and is in a confusing place.

describe the solution you'd like
Make the button appear where the top of the new pasty would be. Also change the text to say "Add new pasty", to more accurately describe the effects of the button.

describe alternatives you've considered

additional context

This would look a lot better imo.

Pls assign to me so I can say I did something useful pog
