Fix naming remotes issue

@noeliasfranco, @alphaGit, @matiasbeckerle

Some Git GUI works in a special way against `origin` remote, for example is the default related remote when a branch is not tracked and also GitHub for Windows only supports one remote called `origin`. 

For that reason, I propose name `origin` the most commonly "pushing to" remote, in the case of DCA flow is the personal fork.

Do you agree?
