[Applications][Linux] Add a tool to launch applications

This tool will launch an Application using its AppID (either via
parameter or via argv[0]).  It will talk to Crosswalk using the
'org.crosswalkproject.Running.Manager' and
org.crosswalkproject.Running.Application' to run and follow the
Application lifetime.

On tizen, this tool will use the appcode infrastructure to get more
information about the launched application state.
