Implements the cdc_stream client and adjusts asset streaming in various places to work better outside of a GGP environment. This CL tries to get quoting for SSH commands right. It also brings back the ability to start a streaming session from asset_stream_manager. Also cleans up Bazel targets setup. Since the sln file is now in root, it is no longer necessary to prepend ../ to relative filenames to make clicking on errors work.
