Added instructions and all-in-one script to use i3 windows manager (#4482)

* Add files via upload

* Open XServer XSDL before running 'starti3'"

* Updated i3 to 4.18.3 and moved the script

* Made the script section more simple and the script will auto recover the variable when exit i3

* Replace `initsommelier` with `startsommelier`
