BAppServerLink is now using BApplication::fServerTo/From for its messaging.

Browse Source 
Added LinkMsgReader::NeedsReply() method.
Completely redone ServerApp messaging: no more "replyport" from BAppServerLink; instead,
the registered client reply port is used. Fixed some more weak messaging stuff.
ServerApp now recognizes if an unknown message needs a reply, and sends it - for example,
the "Screen" preferences app no longer hangs, but crashes on start :)
Made LinkMsgReader::Read() virtual again, since it's needed by RAMLinkMsgReader.cpp.
Renamed BPortLink::GetNextReply() to GetNextMessage().
Some more cleanup.
