Fix simulations using libxmds on Mac OS X Mavericks (loading from binary .xsil files).

The feature of being able to load from binary .xsil files should be deprecated as it requires using libxmds from XMDS-1.  Loading from HDF5 should be used instead.  In fact, binary .xsil files should be considered deprecated.  Maybe we should add a warning to this effect?
