Upgrade checking code is now here, along with a bump of the Gallery

module to v46.  There's a new block in the admin dashboard which
controls whether automatic checking happens, and lets you check
immediately.  If a newer version is detected, a site status message
appears for admins providing upgrade instructions.

Automatic checking is not yet implemented (even though the UI claims
that it exists).  This is all for #1605.
