Add repo owner to alias url.

[zpnk]

The current alias structure is of the form: {repo-name}-{my-branch}.

I think we should add the repo owner to the alias, for example: zpnk-hello-world-some-changes.

This will prevent collisions on project forks, etc.

Is there any reason you don't use a hash or anything to practically guarantee collisions altogether?

For instance, if you pulled the branch's latest commit, you could take that commit's hash's first 7 digits and integrate it into the alias, similar to how non-aliased now deploys get named package-name-hashgoeshere.now.sh.

If you did this, the structure could be {user-name}-{repo-name}-{branch-name}-{commit-hash}. Granted this may be too long at this point, so you might consider cutting out the branch-name since that's now redundant, I think
