Move the handleMessageSecurity and handleMessage hooks after the call
to securityManager.checkAccess.
Benefits:
* A handleMessage plugin can safely assume the message will be
handled unless the plugin itself drops the message, so it doesn't
need to repeat the access checks done by the `handleMessage`
function.
* This paves the way for a future enhancement: pass the author ID to
the hooks.
Note: The handleMessageSecurity hook is broken in several ways:
* The hook result is ignored for `CLIENT_READY` and `SWITCH_TO_PAD`
messages because the `handleClientReady` function overwrites the
hook result. This causes the client to receive client vars with
`readonly` set to true, which causes the client to display an
immutable pad even though the pad is technically writable.
* The formatting toolbar buttons are removed for read-only pads
before the handleMessageSecurity hook even runs.
* It is awkwardly named: Without reading the documentation, how is
one supposed to know that "handle message security" actually means
"grant one-time write access to a read-only pad"?
* It is called for every message even though calls after a
`CLIENT_READY` or `SWITCH_TO_PAD` are mostly pointless.
* Why would anyone want to grant write access when the user visits a
read-only pad URL? The user should just visit the writable pad URL
instead.
* Why would anyone want to grant write access that only lasts for a
single socket.io connection?
* There are better ways to temporarily grant write access (e.g., the
authorize hook).
* This hook is inviting bugs because it breaks a core assumption
about `/p/r.*` URLs.
I think the hook should be deprecated and eventually removed.
