From Andreas Ekstrand, "Attached is a modified ReaderWriterDAE.cpp which creates the one and

only DAE instance when it's first needed instead of in the constructor.
This fixes the problem with osgdb_dae.dll not being loaded due to
unwanted ordering of global initialization.

This fix and the previous fix of the COLLADA plugin might be unnecessary
with the latest COLLADA DOM, but since many of us will probably still
use the older version of the DOM, I guess it's better this way.
