Enforce host user when using Docker as runtime

[marcodelapierre]

Hi Vanessa,

based on my experience, I'd recommend adding the following flags to all aliases and commands when using Docker:

-u `id -u`:`id -g`

This should work with most Linux'es (tested with Ubuntu, Centos, SLES, CLE).
In this way, files created in the host by the container will have the right ownership.

[edited]: inverted quotes ` ` are better than $( ) as they also work in csh.

Ah good thinking, I'll add this. It does seem like a reasonable default, but if someone has issue in the future we can include a setting to enforce.
