Move test.unit.locale out of gettext's way

When I run unittests on my laptop I get an ImportError from gettext who tries
to "from locale import normalize" and says "ImportError: cannot import name
normalize".  Whit this patch unittests works, not sure why this problem
doesn't show up in my other dev environments.

Also this seems like good form since 'locale' is already a stdlib module.

Add flag to stop swob from always using absolute location.

This is needed for SOS (along with patch
https://github.com/dpgoetz/sos/pull/37)
to work with swift 1.12 . By spec you should always use the absolute
location but this causes a problem with staticweb over a cdn using a
cname. Basically you want to be able to forward the browser to a
relative location instead of whatever full url the proxy server
thinks you are using.
