Currently, the status dialog fetches the preferences and system
services that it uses to display connectivity information (e.g.,
IP and MAC addresses) only when the dialog is first opened. This
is fine because the connectivity information is only filled in
once and never updated.
In order to have this information update dynamically (like the
rest of the dialog), fetch and cache these objects in onCreate.
The next change will actually make this information update on
network changes.
