Checked in Macro Jez's additions to osgText to support .osg IO make it

a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.
