Version 2.2 Multi-level menu

Version 2.2 includes such improvements as:

1. 2 variants of the mobile menu.
   
   
2. We made three options for adding a menu to a container (Container is the first line in the settings via, which you can select any place on the page where you want to add a menu).
   Three options work like this:- Replace - the added menu will overwrite the container
   - Appaned first - the added menu will appear at the beginning of the container
   - Prepend last - the added menu will appear at the end of the container
   
   
3. Support fontawesome.com, replaced the arrows.
   
   
4. Redid the mechanism for rendering scrolling.
   
   
5. Improved work when scaling when the font size in the menu is increased or decreased.
