Linking containers broken

This is the error I receive when I try to link a container to an existing one:

    remote: 2014/11/08 17:24:24 Invalid repository name (Linking), only [a-z0-9-_.] are allowed
    ......
    remote: #################################################
    remote: Something went wrong, trying again.
    remote: Killing the container we just launched.

The error seems originated by the `echo` in `/usr/bin/octo`: the String echoed arrive in the variable `RUN_OPTIONS` in [`/home/git/receiver`](https://github.com/octohost/octohost/blob/master/bin/receiver.sh#L44)

Removing the two echo fixed the problem in my octohost.
