Refactor ButtonLayout module components

- Rename ButtonLayout module to just Buttons

- Rename ButtonLayout into AutoDirectionLayout and move it to Base,
  it's useful not just for buttons

- Rename OtherButton into GroupButton, which is now the base of all
  other Buttons buttons

- Add generic (Positive|Middle|Negative)Button components, which are now
  the base for (Apply|Cancel)Button
