Changes for Keith to develop the new profile picker:
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.
