User pages needing work

[Shaun McCance <shaunm gnome org>]

user-add.page
user-changepassword.page

The password dialog has a field for a password hint. I set one, and
couldn't see how to access it from the login screen. Somebody needs
to talk to the developers to figure this out, then put a blurb in
each of these pages.

Probably a single paragraph after the <steps> is sufficient. If
possible, use the same paragrpah on each page to reduce burnen on
translators.

user-forgottenpassword.page

I have a comment in here about what I'd like to see. The two grub
sections can be combined, I think. The only difference is how you
get into grub when booting. Just say something like "Hold down Shift
while booting. On older systems, you may have to press Esc repeatedly
instead."

There ought to be a way to do this if somebody else has an admin
account. The password change dialog does still ask for the current
password, so it might require a hack to get around. But it should
be doable, and I think that's the least drastic way. Figure that
out and add that as the first section.

Thanks,
Shaun
