all hardwired cluster urns and urls.

things were changed.

Also includes some PhantomNet-specific restrictions (e.g. only
allows use of the main Utah Emulab testbed  aggregate).

This excercise stretched the limits of what we can reasonably do
before introducing real per-testbed branding/policy mechanisms to
the php/web front-end.  My changes ain't exactly pretty...

Please take care when adding any testbed-specific changes to the
code.  There are three flavors now to consider in the logic.

intended to finish, but never did. Unfortunate since we have lost some info
that might have been useful.

In addition, we now record provenance on a plain profile copy, in addition
to a clone.

Fixes to the profile history display, and add a new pointer to the profile
derived from when it is not null.

changes and some checks to prevent a user from instantiating a disabled
version.

1. Instead of a plain list of profiles, generate a more detailed list that
   includes last used and usage counts and project name and favorite flag,
   so that the new picker can be sorted/grouped.

   This list is *ordered* by most recent usage (if a real user), or most
   popular (if a guest). 

2. Move the modal from quickvm_sup to the template, and generate the
   current list from the new json info.

3. Add new table apt_profile_favorites to record favorite profiles for
   users.

4. Add new ajax calls for above, MarkFavorite and ClearFavorite that take a
   single argument, the uuid of the profile. There is no UI for this, Keith
   is going to add that.

does all its work via ajax and checks form values along the way instead of
all at once at the end.  Guest verification works in this version.

Useless for two reasons:

1) It just takes them back to a page they already had to go through to
log in

2) For some reason, it was linking the pre-release version of the site,
before it went live, so the link was wrong anyway!

For some reason, the padding applied by bootstrap was causing this
to make the container go slightly off-center. Removing this class seems
to have no ill effects.

Ultimately, this needs a lot of rewriting to make the control flow
more obvious and less fragile.
