Fix directory creation when installed as a local module

[Tug]

When running:

var pm2 = require('pm2');
pm2.connect(function(err) {});

after installing pm2 locally, this is what I get:

[PM2] Spawning PM2 daemon

fs.js:432
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^
Error: ENOENT, no such file or directory '/Users/polo/.pm2/pm2.log'
    at Object.fs.openSync (fs.js:432:18)
    at Object.launchDaemon (/Users/polo/Work/nirror/nirror-server/node_modules/pm2/lib/Satan.js:314:14)
    at /Users/polo/Work/nirror/nirror-server/node_modules/pm2/lib/Satan.js:52:20
    at /Users/polo/Work/nirror/nirror-server/node_modules/pm2/lib/Satan.js:372:14
    at process._tickCallback (node.js:419:13)

I guess a quick fix would be to copy paste the code from CLI.pm2Init in Satan.launchDaemon.
