[Engine/Engine-*] Refactored IProtocolManager.Connect() to use ServerModel

Cleanly pass all connection parameters to the protocol manager using the
ServerModel class. This way it is no longer needed to add and save a server
before making use of SSL options.

Also it will make it easier to add multi-identity support (references: ~~#428~~),
different encoding per server (references: #27),
client certificates (references: ~~#96~~) and SASL support (references: #98).

Engine(-IRC), Frontend-GNOME: support CertFP (closes: ~~#96~~) as an more secure alternative to the famous "/msg NickServ IDENTIFY my_password"
command.

https://freenode.net/certfp/

As this is an internal setting only (for now) you need to configure it using
the /config command like this:

/config Servers/IRC/$SERVER_ID/ClientCertificateFilename = mycert.pfx

/config save

The client certificate can be generated using makecert like this:

makecert -eku 1.3.6.1.5.5.7.3.2 -r -cy end -n "CN=$USER" -p12 mycert.pfx ""

The certificate must not use a passphrase, else it can't be loaded. Thus secure
the file against access by other users with:

chmod 400 mycert.pfx

Place the certificate in ~/.config/smuxi/certs/ otherwise specify the full path
in ClientCertificateFilename.

On most IRC networks that support CertFP you can verify if the certificate was
used using /whois on your own nickname. A line like this should show up in the
whois reply:

[276 (?) meebey3] has client certificate fingerprint a15aecab43e1d0965a2da43739a9628d790994e0

Special thanks goes to An-Ivoz for finding out how client certificate selection
works!

Target version changed from 0.8 to TBD

CA certs need to be imported into Smuxi and the CA store needs to be populated at runtime somehow... SslStream doesn't need to offer a simple API for this :/
