Replace icon-hamburger-menu

There is a component used for the hamburger icon on the main menu: icon-hamburger-menu. We built those before we introduced rcc-icon. Please replace all occurrences of buttons that use icon-hamburger-menu with small action buttons. ( I think it's just the main menu )

You may have to add a new icon (the hamburger icon): If need be use the old one and remove color information.

You may also have to add a color to the buttons; use colorCatgory: 'secondary' for that.

Requirements

• HamburgerMenuComponent removed from the code
• buttons, that used icon-hamburger-menu, still work and look very much like before 😄
