Patch from Dan Scott to entity-ize a chunk of the Staff Client interfaces:

Taking this one step at a time, I'll move the remaining hard-coded
strings from main/*.xul into lang.dtd.

I've also followed the same ${locale} approach for the remote XUL
files rather than having the en-US hard-coded into the XUL files
themselves -- although at the moment we don't really have a good way
of serving up a different locale anyways. Accordingly, I've included a
modification to eg_vhost.conf.

lang.dtd is getting very big. To try to make it a bit easier to work
with, I've sorted the bulk of the UI entity definitions as seemed to
be the general intent (a few had fallen out of order) so the diffs in
this patch are a little more than absolutely necessary; sorry about
that.
