Add your Github token to existing remotes

addtoken.sh

## If you have to create a Github access token (e.g. if you enabled two-factor auth for the same time)
## and you used https:// formatted git remotes for all your local repos, you won't be able to push
## or pull anymore. This allows you to fix all your remotes whenever you need to with a simple
## bash alias.
##
## Put this in your ~/.bash_profile or ~/.zsh_profile, then run `$ fixremote` in a repo directory
## to fix it.
##
## P.S. You should use SSH remotes for your Github repos. But if you're behind a corporate proxy
## that messes up SSH to the public internet, you can't... :(
