ITFTalk and ITFListen

Since these work I added these in first. The ITFOpenEar stuff is still in there, but commented out until we can fix the pthread.h issue. Other useful tidbits of information:
* ros_nmpt_saliency - Mandeep's version commented out and replaced with my version from Jamie's repo
* Octomap disabled as it breaks the build (not sure how / why this addition was accepted?)
* Renamed tags in Dockerfile from the original 'blender' to 'zenorsm'
