From Colin McDonald, "The bsp & mdl plugins have calls to atof() without including the

associated <stdlib.h> header.  This breaks the build on my Solaris setup.

Rather than adding the missing <stdlib.h> include, I have changed the
atof() calls to osg::asciiToDouble().  This is the same as was done
throughout the other plugins recently, for locale independance.

I've attached updates to the svn trunk, the fix is also appropriate for
the 2.8.* branch."
