Rethink config/default & keybindings

+ Added +smartparens flag to config/default for default smartparens
  config.
+ Fixed +tng support for completion/company.
+ Removed super keybinds (for all but MacOS)
+ Moved "keybind fixes" to config/default/config.el (these should be
  universally available).
+ Replaced both +default-repeat-forward-key and +default-repeat-backward-key
  with +default-repeat-keys. If this variable is nil, the universal
  repeat motions won't be bound.
