User interface updates & improvements

We've updated our user interface again - we're now using the available screen space much better. In case you've added your own background image you will see that the sidebars on the left and on the right are semi-transparent!

What has been updated in detail?

• 100% width of the whole window (with auto-resizing)
• Album artwork has been moved to the left bottom corner
• Currently active playlist will be highlighted
• Search history moved to the bottom in the left sidebar
• New search box in the search tab
• Sidebar on the right clean up - now with recommendations!
• Rating / Add to playlist actions for every track now in the bottom bar
  
• New popup menus will automatically fade out
