updated to new automake and refactored server stuff. the server

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CServerProtocol classes have been replaced by CClientProxy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.
