now speaks to the primary screen and secondary screens almost
everywhere the same way through an IClient interface; only
special primary screen calls are accessed through a different
interface, the CPrimaryClient interface. this simplifies the
server since it no longer needs to test whether the active screen
is the primary or a secondary in most cases.
the server no longer speaks directly to the primary screen; all
that goes through the CPrimaryClient, which often just forwards
the call. the primary screen no longer speaks directly to the
server either, again going through the CPrimaryClient via a
IPrimaryReceiver interface.
CServerProtocol classes have been replaced by CClientProxy
classes which are very similar. the name makes more sense
though.
