ZNC: Update configuration template for znc 1.4

ZNC 1.4 uses a new section within the configuration file to specify
password hash and salt. This requires adding a new Ansible variable
'irc_password_salt'.

Also update the README file to reflect above changes.
Make the test suite work with latest Vagrant configuration

Adjust cipher suite assertions to match what's currently reported by the
server.

Remove WebTests.test_znc_http test since ZNC web interface isn't exposed to
the Internet.

(Tested only with Debian 7 VM from the Vagrantfile)
