Disable reservations; subnet enable/disable buttons; page-head CSS fix
release / release (push) Successful in 5m53s

- A disabled reservation is kept but ignored: the client gets a pool
  address like any other (steward reservation disable|enable, buttons and
  a checkbox in the web UI). Schema migration 3.
- Subnets get Disable/Enable buttons on their page and in the list.
- A rule left without its selector in style.css broke the page heading's
  layout, so the New ... buttons sat cramped under the description.

* **A device on two VLANs** can have a reservation in each subnet. Within
one subnet, a client has at most one.
A reservation can be **disabled** (`steward reservation disable RES`, or
Disable in the web UI). It is kept but ignored: the client gets a pool
address like any other, and the reserved address, if it is inside a pool,
may go to someone else. The client keeps the address it has until its
lease runs out. While it is disabled, another reservation may use its
address or client; enabling it again is then refused until one of them
moves.
A client with a reservation always gets that address, not a pool address.
If it asks for another one, for example after the reservation was added,
it gets a NAK that names its reserved address, and then the reservation.
