Hornwitser dbe01c6c23 Decode master secret from base64 (#398)
The jsonwebtoken accept strings as input for secrets which is
nonsensical from a cryptographic standpoint as the algorithms all
operate on byte sequences.  Worse still, strings are encoded into bytes
using UTF-8, which disallows certain sequences of bytes from appearing
and potentially weakening the cryptography.

For legacy reasons the master secret was encoded into base64 _and passed
as a string to jsonwebtoken_.  This further weakened the crypto as the
bytes that can appear in base 64 is only 1/4 of the 256 possible values
for bytes.  This could significantly weaken the cryptographic strength
of the tokens.

I have known of this issue for quite some time but has put off actually
fixing it for too long now.  Since the master secret is already
documented as being in base 64, decode it as base 64 and pass it as a
byte Buffer to jsonwebtoken.  This will ensure every byte value is
possible in the byte sequence passed to the jsonwebtoken crypto.

The impact of this change is unfortunately that all tokens will become
invalid and will have to be reissued.

Hornwitser d6f09f4c1a Fix close during reconnect wait period
If the connect close method is called while the connection is waiting
for a reconnection attempt then the attempt is cancelled but the close
method then erroneously waited for a close event that would never
happen.  Fix by resetting the connector and rasing the close event in
the close method if it's in the waiting for reconnect state.

Hornwitser 1de8b76303 Emit resume instead of connect on resumed connections
Raise "resume" instead of "connect" when a connection is re-established
after a connection drop.  This prevents logic meant to resynchronize
state after a full reconnection from being invoked whenever the
connection was temporarily dropped.

Hornwitser 3592ff3269 Remove automatic creation of TLS certificate
The automatic creation of a self-signed certificate while nice presents
several problems.  To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.

To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server.  These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.

For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly.  This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
