- Rename ButtonLayout into AutoDirectionLayout and move it to Base,

other Buttons buttons
- Add generic (Positive|Middle|Negative)Button components, which are now
the base for (Apply|Cancel)Button
- Refactor everything about HBox, and adapt all the pages and popups
that used it
- Replace HTabContainer by HTabbedBox

- Make esc presses in boxes click the cancel button
- Make all boxes and popups scrollable when needed
- Replace generic apply button icons in popups
- Fix tab focus for error and invite popups
- Rework (still WIP) the account settings page:
