Use a smaller statusbar by default

As per discussion in #50

This adds following changes:

• Disable zoom and space information settings in statusbar by default
• If zoom and space information in status bar are off, show a small statusbar
  • This statusbar overlays on top of the items instead of taking space
  • It changes size according to content
• If zoom and/or space information are on, show original statusbar
• If user navigates with keyboard, or scrolls to selection, the scrolling will take the statusbar into account

The basic idea is to have something similar like in Firefox when you hover over a link. However if user wants to have the zoom slider or space information, the statusbar goes back to the original looking one.

Small statusbar	Regular statusbar (no changes)
