I moved trunk/include/ruby/node.h to trunk/node.h.  On 1.9, only
include/* files are installed, so node.h is no longer installed
file.  This is because saving ABI.  node.h includes version
sensitive structure, and there is a plan to change it after release
1.9.1.  So we decided to move it.

If some extension rely on node.h of 1.9.1, the extension can not be
used by 1.9.2 or later.

Any comments?
