Smartparens addon for deletion commands (mostly)
I noticed that a lot of delete commands were leaving the yank system dirty, especially since they're put in terms of their respective kill-commands, shadowing the kill-ring but not covering kill-ring-yank-pointer.
I wasn't sure if it was worth the effort to try and fix the hack with more hacks, and honestly i just wanted feature additions, so i just made an addon instead.
