This has been moved into its own directory so that we can use a makefile to
generate it.  Later, we will add automatic version info to the document to
show the exact version of Trilinos this document refers to.

I also removed the generated files for Trilinos build reference.

From now on, these will be generated on demand so they are always up to date.
