Make Small screen menu more Material, also add persistant/te

When the screen become small, instead of showing the menu the bootstrap way as a simple list, we should display them in a little popup. Demo: https://material-components-web.appspot.com/simple-menu.html The bootstrap menu always was very ugly :P   Also would be cool to add a temporary or persistent drawer For inspiration look at https://material-components-web.appspot.com/ Now, someone would drop by and say: Use both! But Font Awesome 5 RC2 and this makes 2.2Mb (minified with css and js), anyone sane won't add anything else to this insanity. MDB is a huuge library but adding a few features won't make it a megabyte bigger. They are official Material designer, they don't use bootstrap though they only develop Material stuff (that's why I don't use them, I love bootstrap it make life so much easier) Take also a look at their amazing lists: https://material-components-web.appspot.com/list.html Cheers - Keep up the good work!
