Work around a memory corruption bug in XML, set default port correctly.

src/e-server:
	* src/ServerInfo.cpp: portNum initialized to
	DEFAULT_RSP_PORT.
	* src/ServerInfo.h: Define DEFAULT_RSP_PORT.
	* src/main.cpp (initPlatform): Do not delete xml at
	end of function, since it causes stack corruption. BUG TO BE FIXED.
