This just changes Nek5000/core/make* to use libmesh_LIBTOOL and the
assoicated flags.  This is NOT a substitute for a more extensive
overhaul of the build system.

TODO: Set or discover $LIBTOOLFLAGS as in the MOOSE makefiles.

Added run script for MOON problems

example problem utilizing objects.

build script creates dummy include/ and src/ dirs

The MOOSE build script expects a couple of subdirectories in the app directory (include/base and src/).  These aren't available in the Nek+MOOSE example directories, so the MOOSE build script will throw some (harmless) warnings.  The changes to the build script will create empty include/base and src/ directories if those don't already exist.
