i see green tests

but there is still one error, and a challer choosing test is a dummy one
so i will fix them later
it took me about 10 minutes to write this (there was a cigarette in the meantime)
github authentication, navbar, adding order & item

GH auth still got one step too much, to fix
it's 1st time I'm using this kind of authentication and gem, so it took me about an hour to
read doc, generate api secrets, use it etc

one can add order and one item to it

I noticed that some validations are missing, have to add them, I'm not so effective
at late night apparently...

attached photo of my handdraw idea for the app :)
