Add smaller statusbar and set it as default

- Statusbar has three modes: Small, FullWidth and Disabled
- FullWidth is the original statusbar
- Small is the new default statusbar
  - This statusbar overlays on top of the items instead of taking space
  - It changes size according to content
- Disabled turns statusbar completely off
- Zoom slider and space information is only shown in full-width statusbar
  - Space information is now always on
- If user navigates with keyboard, or scrolls to selection, the scrolling will take the statusbar into account
  - This makes sure the statusbar does not cover any items
