Made the following name changes to Matrix and Quat to clean them up and make

the functionality clear given the name.  This will break user code unfortunately
so please be away of the following mapping.

  osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
  osg::Matrix::makeRot(..)?\026   -> osg::Matrix::makeRotate(..)
  osg::Matrix::trans(..)?\026     -> osg::Matrix::translate(..)

  osg::Quat::makeRot(..)?\026     -> osg::Quat::makeRotate(..)

Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.
