* move init functions from routers/install to routers/init

* copyright typo

* Handle user ssh key input better

ssh_key: when user submitted keys had a newline at the end, strings.Split
would have created a slice with an empty last element, and the key type
check would be incorrect. Perhaps a better way is to look for 'ssh-rsa' or
'ssh-dsa' at the beginning of the string, but this is simple.

* ssh_key: correct indentation

go lint fixed for routers/admin
