Added host() and port() to Builder

[KennedyTedesco]

This is just a proposal because i prefer more fluent like that:

server('name')
    ->host('ec2-52-171-208-37.my-server.com')
    ->port('9876')
    ->path('/home/dir/dir')
    ->user('user')
    ->pubKey('~/.ssh/name.pub', '~/.ssh/name');

instead of:

server('name', 'ec2-52-171-208-37.my-server.com', '9876')
    ->path('/home/dir/dir')
    ->user('user')
    ->pubKey('~/.ssh/name.pub', '~/.ssh/name');
