Create left side panel

[thejhh]

Instead of a dropdown menu, we want the main features of the application to be on left side as links. Just the same way as it is in many other apps.

• Currently it would contain only Home and Users
• Add icons for Home and Users
• If the screen is small, only show the icon
• Button to make it compact (only icons visible)
• Remove links from the AppHeader
