Tweak non-English editions wording in admin
Adjust select for non-English editions

We shouldn't include English in select options. This has necessitated
a tweak to the controller to remove the locale parameter if the
submitted value is blank.

Non english edition tweaks
Preload Whitehall in production

The time before the app begins serving requests is currently quite large
due to the way Rails lazily loads its object graph. During this time it
times out frequently while it warms up.

This commit tells Unicorn to preload the entire application, and
includes the standard database connection futzing that seems to be
common to these solutions.
