Renamed osg::Matric::makeIdent() to osg::Matrix::makeIdentity() to make

it consistent with the rest of the osg::Matrix naming.  Updated OSG
distribution to account for new name.

Added support for the STATIC/DYNAMIC osg::Transform::Type to the .osg
ASCII reader/writer plugin and the flt reader plugin.

Removed the non cost version of osg::Transform::getMatrix() as this could
by pass the dirty mechinism.
