Removed nta git submodule, replaced with CMake commands to manually clone,
fetch, and checkout nupic.core repository.  This also allows overriding the
defaults on the command line via NUPIC_CORE_REMOTE, for the remote repository
url, and NUPIC_CORE_COMMITISH, for the specific sha.

Specify WORKING_DIRECTORY in git fetch
lower-case "set" for consistency
