Option to embed settings.json file inside exe

```
If settings.json resource is embedded in exe then use it, otherwise check for 
settigs.json file in current directory. This command can be used for embedding 
(found in node-webkit examples):

  copy /b phpdesktop.exe+resources.zip phpdesktop.exe

```
