[polari] serverRoomList: Use a template

[Florian Müllner <fmuellner src gnome org>]

commit 2934dc374cd9e1acb264dbf8781fe217261e7a18

    serverRoomList: Use a template
    
    We will soon move some bits from the joinDialog hierarchy into the
    serverRoomList, so it's a good time to make it use a template - though
    moving the tedious TreeView setup out of the code is already quite nice
    by itself ...
