1.1.0

usage: install | start | status | stop | upgrade
big update:
1.add 'upgrade' command, use this command to update your kernel to latest version
2.'install' command defaultly and only provide a latest kernel version, instead of v4.11.0, maybe ver1.2 will add a alternative function
3.made shell language a great modification, use better determination arrangement
4.have a colour style modifictaion, and fix few little issue
from my plan, ver1.2 should release little soon, trying to provide more manual work.
