/**
* @class ServerListModel
*
* This class defines the model for visualising a list of matrix servers.
*
* The list of servers is retrieved from the local cache. Any additions are also
* stored locally so that they are retrieved on subsequent instantiations.
*
* The model also automatically adds the local user's home server and matrix.org to
* the model. Finally the model also adds an entry to create a space in the model
* for an "add new server" delegate.
