Added safety guidelines and updated the README!

I checked the resources tab yesterday and realized my README was not up to par! So I decided to make it as polished as possible and also forgot to log some of the hours! oops :P

Anywhooo the readme has been updated so that now most people who have a basic understanding of robotics stuff can make my project! If any of you guys choose to make this, please let me know! I think it would make a great little HCB prize if I’m being honest.
