Convert cmake build to (mostly) use urls rather than git clones (#852) Exception: grpc. Due to it's use of git submodules, it's not completely trivial to convert it (though probably wouldn't be too much more work.) This helps address our build being throttled. (Maybe. This assumes github allows more fetching of tgz's than clones.) It should also speed up our build times. The downloaded tarballs are placed into ${PROJECT_BINARY_DIR}/downloads. This allows for eventual caching in travis.
