Add text about redistributing server VM to JRE README.

Text similar to the following should be added to the redistribution section
of the JRE README.

   On Microsoft Windows platforms, the Java 2 SDK includes both the
   Java HotSpot Server VM and Java HotSpot Client VM. However, the
   Java 2 Runtime Environment for Microsoft Windows platforms includes
   only the Java HotSpot Client VM. Those wishing to use the Java
   HotSpot Server VM with the Java 2 Runtime Environment may copy the
   SDK's jre/bin/server folder to a bin/server directory in the Java
   Runtime Environment. Software vendors may redistribute the Java
   HotSpot Server VM with their redistributions of the Java Runtime
   Environment.
