[erlang-questions] Start two same applications at the same time with rebar

Hi,

The default runner script generated by rebar does not support starting two  
or more daemons. The problem is that each daemon should have a unique pipe  
directory, but the PIPE_DIR only contains RUNNER_BASE_DIR.

I would modify the script to recognize the -sname or -name argument and  
append the node's name to PIPE_DIR. (For my project I use a heavily  
customized start script, but I think this was the crucial part in enabling  
multi-node startup.)
