uid in chroot context

[yotamr]

When running dwight through sudo, the uid in the chroot environment is 0 as well. It's desirable to have dwight command run in the same context of the calling user. I don't have a clean solution, here are some ideas:

1. Since most dwight invocations are through sudo, dwight can use the SUDO_UID environment variable to setuid() to the original user and setuid(getuid()) in case $SUDO_UID doesn't exist
2. setuid the Python interpreter - probably a bad idea.

I like the SUDO_UID option better. I can also provide an option to specify the uid just in case.

Is the guid also handled in a similar fashion?

Nope - I forgot to add the GID option - adding it now.
