Checkpoint various changes.
* Various UI tweaks for profile versioning. * Roll out profile versioning for all users. * Disable/Hide publishing for now. * Move profile/version URLs into a modal that is invoked by a new Share button, that explains things a little better. * Unify profile permissions between APT/Cloudlab. Users now see just two choices; project or anyone, where anyone includes guest users in the APT interface, for now. * Get rid of "List on the front page" checkbox, all public profiles will be listed, but red-dot can still set that bit. * Return the publicURL dynamically in the status blob, and set/show the sliver info button as soon as we get it. * Console password support; if the aggregate returns the console password, add an item to the context menu to show it. * Other stuff.
